Adjournment ROLL CALL All members were present and a quorum was established AGENDA APPROVAL Mr. Ventress motioned, Ms. O'Brien seconded to approve the agenda as presented. The motion carried unanimously. APPROVAL OF 11/09/16 MEETING MINUTES Mr. Hirniak motioned, Mr. Ventress seconded to approve the 11/09/16 meeting minutes as presented. The motion carried unanimously. AUDIENCE COMMENTS None 2016 ANNUAL REPORTS Ms. O'Brien reported that the Clam Bay Annual Monitoring Report (completed by Earth Tech) and the Clam Pass Annual Physical & Tidal Monitoring Report (completed by Humiston & Moore) have been submitted to the PBSD and included in the agenda packet. The Clam Bay Annual Water Quality Report (subcontracted by Turrell Hall to Dr. David Tomasko of E.S.A.) is expected to be received within the next week. The committee agreed that these three reports would be provided to the PBSD full board at the January 2017 board meeting. Ms. O'Brien highlighted good news in the Clam Bay monitoring report including, (1) archeological sites are undisturbed, (2) canoe trail markers are in good condition, (3) the locations of exotics have been mapped, providing the ability to target these areas, (4) the population of gopher tortoises has increased, (5) the acreage of sea grasses has increased to 5.5 acres from 4.7 acres, (6) a comprehensive list of protected species in Clam Bay has been compiled, and (7) eight new monitoring plots have been added in the mangrove die-off area. Mr. Jeremy Sterk commented that the mangrove die-off area appears stable at 11.5 acres. He has observed some additional areas of"stressed mangroves" which cannot be detected in the aerial photos. Despite zero rain during the past two months, water levels have not receded. Dr. Mohamed Dabees commented that Clam Pass is healthy and in good condition from a hydraulic standpoint. Mr. Dorrill asked for comments on the current existing beach escarpment. Dr. Dabees commented that his observations show that the escarpment is currently self- correcting and does not meet the turtle nesting corrective action requirements. He concluded that no action should be taken at this time. MANGROVE DIE-OFF THA NOVEMBER REPORTS AND DECEMBER OBSERVATIONS 2 Pelican Bay Services Division Clam Bay Committee Meeting December 19,2016 Mr. Tim Hall reported that the original mangrove die-off area remains steady at 111/2 acres, with one additional small stressed area just south of Marker 36. He recommended obtaining an elevation survey to include the die-off areas and the area adjacent to the wall along the Strand. Subsequent to Mr. Hall's review of an elevation survey, he will re-evaluate the need for additional hand-dug channels. Ms. O'Brien suggested that staff obtain a rough estimate for the elevation survey to provide to the full board for discussion. Ms. O'Brien commented on ABB's recent reporting that water is draining from Bay Colony into the conservation area. She suggested that staff meet with Bay Colony management staff to address this issue. WATER LEVEL LOGGER DATA Mr. Sterk commented that the loggers have indicated high water levels since July. EXHIBITS OF HAND-DUG CHANNELS Mr. Hall commented that he has observed no blockages in the hand-dug channels and believes the channels are functioning properly. He believes the mangrove die-off is a result of last year's constriction of Clam Pass, and that it will take time for the recruitment of red mangroves into the die-off area. CONSERVATION EASEMENT NEAR THE STRAND AND PROPERTY LINE No further discussion. Discussed under agenda item#6a. APRIL 2002 COMMITTEE MEETING MINUTES Ms. O'Brien commented that the minutes from the April 2002 committee meeting were included in the agenda packet as background information. These minutes included committee discussion points on the original mangrove die-off Ms. O'Brien highlighted (1) our current drainage issues are similar to those in 2002, and (2) these minutes specifically state that "mangroves cannot tolerate standing water over a long period of time." Ms. Mary Johnson expressed concerns regarding sea level rise and possible effects on Clam Bay. Mr. Shepherd commented on the possibility of straightening water flow by "cutting" the oxbows. Mr. Hall commented that this strategy would require permitting and proof that such a project would directly solve the mangrove die-off INTERVENTION STRATEGIES Ms. O'Brien recapped the intervention strategies agreed upon by the committee as (1) PBSD staff will meet with Bay Colony management staff to address their clogged drainage systems, and (2) staff will obtain a rough estimate of an elevation study of the die-off areas and the area adjacent to the wall along the Strand. CLAM BAY MONITORING IN 2017 RECOMMENDED CHANGES TO 2016 MONITORING Mr. Sterk recommended the following changes to the 2017 Clam Bay monitoring: (1) increase monitoring of the mangrove plots in the die-off area to semiannually, (2) discontinue monitoring the remaining Lewis plots, (3) add tortoise population monitoring, (4) add scaevola 3 Pelican Bay Services Division Clam Bay Committee Meeting December 19, 2016 (type of exotic plant) monitoring in order to target removal, and (5) add additional mapping of hand-dug channels. ADDITIONAL MONITORING OF MANGROVE PLOTS IN DIE-OFF AREA Mr. Sterk recommended semiannual monitoring of mangrove plots in the die-off area. BATHYMETRIC SURVEY OF INTERCONNECTING WATERWAY BETWEEN INNER AND UPPER BAYS Dr. Dabees suggested the cost effectiveness of obtaining a bathymetric survey of Clam Bay to include areas of Inner Clam Bay and Upper Clam Bay, to be completed simultaneously with the elevation survey, by the same surveying crew. WATER QUALITY MONITORING After discussion, the committee decided to delay a decision on change in frequency (from quarterly reporting to semiannual reporting) of water quality monitoring by Dr. Tomasko until after the 2016 Annual Report is received and reviewed. NEXT MEETING: FEBRUARY 2,2017 By consensus, the committee agreed that the next meeting of the committee would be held on February 2 at 1:00 p.m. ADJOURNMENT rThe meeting was adjourned at 2:49 p.m. Susan O'Brien, Chairman Minutes approved [ 1 as presented OR [ 1 as amended ON [ 1 date 4 Agenda Item#5a Page 1 of 12 TURRELL, HALL & ASSOCIATES, INC. MARINE & ENVIRONMENTAL CONSULTING 3584 Exchange Avenue, Suite B •Naples,Florida 34104-3732 • (239) 643-0166 • Fax (239) 643-6632 MEMORANDUM TO: PBSD Clam Bay Committee do Neil Dorrill FROM: Tim Hall DATE: December 16,2016 RE: Status report on flushing channels in Upper Clam Bay At the request of the Committee,we have undertaken a review of the flushing channels within the die-off area in an attempt to answer several questions that were posed to us at the November Committee meeting. Specifically; - Why is standing water still present along the Strand wall following a month of no rain? - Which channels are still effective and are there any that are no longer working as designed? - Will digging more channels address standing water still being observed along the Strand wall or elsewhere in die-off area? As we started on this investigation I first wanted to see if the area as a whole was responding in sync with the tidal information the Board has been gathering via the new tide stations. I looked at the past 6 months of tide data from Upper Clam Bay and compared that to the water level logger that EarthTech had installed in the mangroves of Upper Clam Bay. Exhibit 1 attached to this memo is the tidal data for Upper Clam Bay. Exhibit 2 is the water level data from the EarthTech logger place din the mangroves. I noticed spikes in the tidal data on September 1, October 18, and November 15. These spikes corresponded almost exactly with spikes in the water logger data from inside the mangrove system. The September 1 data intrigued me because of how much higher the water levels were at that time compared to the rest of the time period. I didn't think that was the result of tidal flow only. A little more research into the ambient weather that day showed me that On September 1 and 2 we had winds over 20 mph and gusting up to almost 40 mph from the south(See Exhibit 3 weather data from 9/1),which was pushing all that extra water up into Upper Clam Bay. The good news is that the system recovered back to normal water levels almost immediately after the winds dropped in intensity and shifted to a different direction. Based on this data,I believe that the connectivity of the mangrove system to the Bay through the flushing channels is still good and water flow is happening as it was designed. Question 1: Why is standing water still present along the Strand wall following a month of no rain? We also went into the field and investigated the individual channels that allow the flow from the wall to move east through the mangroves out to the Bay. It is clear from these investigations that water is flowing from the wall but that there are pockets of lower areas where water is pooling. I believe that this is a result of lower ground elevations and not blockages in the channels. The below photographs show a couple of different areas along the wall where this elevation difference can be seen.

'y ' 4' I t 2 '> s i The above photograph shows standing water along the wall but not inl the mangroves adjacent. Also shown is the flushing cut which does appear to be working as intended and helps to drain the water away. Areas along the wall are simply at lower elevations where the water cannot drain completely away except at very low tide levels.

These seedlings would not survive if the area was constantly inundated. Agenda Item#5a Page 4 of 12 Question 2: Which channels are still effective and are there any that are no longer working as designed? All of the channels that we have investigated to date were still working. Some exhibited slower flow that others but all were passing water. We have begun calculating small issues that may become larger blockages over time and will be working on triaging these so that maintenance efforts in the coming year can be best spent on areas of greatest concern. The photos that follow depict some of the minor issues that we see arising and that will need maintenance over time. There have been no catastrophic blockages or failures in the channels that would preclude them from working as designed documented as of this time. ,, 4. -. 8 ii , , .,k,,,,, , ,. f 7 ; . , Ift 4 ,...• t 0011 ii.„ ,:„,,, „ . . , . .....„, . ; ..,.,,, ., ,, _ , , , ft.

This is a channel opening into the Bay that is still very open and not in danger of blockage from growth. Question 3:Will digging more channels address standing water still being observed along the Strand wall or elsewhere in die-off area? Based on the flows observed and the general conditions along the wall in the die-off area, I don't think any additional channels at the wall will really help with standing water there. I think it is more of an issue of lower ground levels,either as a result of the construction of the wall or compaction from work and maintenance along that area. We did come across afew spots within the die-off area that were holding water for longer than surrounding areas. It may be possible to improve flushing in these isolated areas with some additional small channels that would tie into the larger ones already in place. We are still mapping these areas along with potential small channel locations to present at a future meeting. Before digging any additional channels,I would like to get some survey information relative to ground elevations through the die-off area from the wall out to the Bay. This will let us know if the standing water is the result of frictional forces holding it back or if it is simply lower ground elevations that would not drain even with channels installed. Most of these areas located so far are close to channels that have been dug already but with just enough distance that they are not reacting as quickly as those areas immediately adjacent to channels and therefore holding water longer to the detriment of seedling recruitment and healthy older trees. We are working on determining where the best locations are for these survey transects as well as potential new channel placements for submittal to the Committee at the January meeting.

Agenda Item#5a Page 9 of 12 Based on the field work conducted to date I do not believe that there is much that can be done with respect to eliminating all the water along the Strand and Bay Colony wall through additional channel construction. If we wanted to fill in that area to match the adjacent ground elevations then that could eliminate the standing water there but would take a substantial permitting effort to be allowed to do so. The area would still be a mangrove wetland, but would be at about 3 to 4 inches higher elevation than it currently is. This will be a difficult concept to get agencies to agree to as in their way of looking at things we would be putting fill into a wetland. However,there may be a few small side channels that could be put in to help out in the interior of the larger die-off area. Survey information would help to make the final determination of the viability of new channels. I would still maintain that the most important item to keeping water elevation down to healthy levels is insuring that water can get from Upper Clam Bay to the Pass. Any blockages in the smaller waterways between Upper and Inner, or between Inner and Outer Clam Bays needs to be monitored and maintained as quickly as possible. This is in addition to the maintenance of the Pass itself to insure that all the water within the Clam Bay system can flow as freely as possible.

Comparison between November's extents and January's show that there has not been any expansion and a couple of the areas appear to be filling a little with canopy leaf cover. This gives the appearance that areas may be recovering but there is still not a lot of evidence of midstory recovery so I still have concerns that extreme weather events (freeze or heavy rains) could still impact the recovering trees. Heavy winds over the past weekend (Jan 21 and 22) resulted in a very high tide level in Upper Clam Bay but the water levels returned to normal fairly quickly and did not stay super elevated. The November report estimated the dead acreage at around 11.66 acres. The last two months have indicated a slight decrease in this acreage but that could simply be due to camera angles and light conditions making delineation of the die-off area a bit different. No changes have been observed in the small area to the south of Marker 36 that was noted in November. We will continue to monitor these areas to see if the recent high water or future cold snaps(if any)have any impact on the stressed areas.

Background Clam Pass is a small wave dominated inlet on the southwest coast of Florida that provides a tidal connection to 500 acres of the wetland preserve of Clam Bay Natural Resource Protection Area(NRPA).This preserve includes several interconnected bays surrounded by extensive areas of mangrove wetlands. The preserve is a pristine environmental resource that is collectively known as Clam Bay. Clam Pass has gone through periods of inlet migration as well as closure, because the relatively small tidal prism for Clam Bay provides critical balance between tidal energy and littoral process at the inlet channel.

Here is my quick summary. Jeremy please feel free to add to it if I forgot anything. 1. Identify channel location(s) and scope or sizes. 2. Create permit exhibits and application. 3. Pre-application meeting with FDEP and USACE. 4.Amend application if necessary based on pre-app comments. 5. Submit application. 6. Coordinate permit review with Agencies and commenting parties(USACE public notice, FWS, FFWCC, possibly EPA, etc.) 7. Potential site visits with Agency reviewers 8. Receive FDEP permit 9. Receive USACE permit Sorry so brief but writing from my phone. Based on recent experience with USACE and FWS I would plan on at least a year to 14 months to get through the review. We could do a lot better but I'd rather plan for worst. Tim Sent from my iPhone • Agenda Item 5g Page 1 of 1 a Lewis Environmental Services, Inc. ''; •,; Roy R. "Robin" Lewis III, President P. 0.

Authorized work must conform with the detailed project description, approved plans, and all conditions including preconstruction requirements included in the final order. A brief description of the authorized work follows. Project Description: The applicant/permittee is authorized to operate two portable diesel powered hydraulic dewatering pumps with 12 inch discharges capable of pumping less than 5,500 gpm in Upper Clam Bay. The pumps may be used on a temporary basis as needed to maintain water levels between 0.5 feet to 0.8 feet NGVD and may discharge excess treated stormwater/rainwater only into the Gulf of Mexico. The use of the pumps is an attempt to lower the high water levels which are believed to be causing the high incidence of death among large areas of mangroves within the system. Project Location: Two discharge locations; one at approximately 400 feet south of the Department of Environmental Protection's reference monument R-30, and the other at approximately 50 feet south of R-37, in Collier County. Project address: Located on Bay Colony Drive(no numbered street address).

In 1995, Collier County created a Mangrove Task Force to investigate the die-off and develop actions, to be implemented prior to the 1996 rainy season, to assist in preventing additional mangrove die-offs in Upper Clam Bay. Itis theorized that the die-offs have occurred due to extremely high water elevations in the mangrove areas. The cause of the high water elevations have yet to be determined. The mangrove dieoff areas on the west side of Upper Clam Bay are shown on Sheet 4 of 7 of the enclosed drawings.• The various actions identified by the Task Force included construction of two overflow structures in the Upper Clam Bay system. However, the initial review of the permit application by Florida Department of Environmental Protection (FDEP) staff,resulted in the suggestion that portable pumps and pipes be utilized in order to meet the time frames of the project. Portable pump #1 will divert treated stormwater into the Gulf of Mexico that normally discharges to Upper Clam Bay. Portable pump #2 will drain water from the Upper Clam Bay system to the Gulf of Mexico. The pumps will be operational during times when the water surface elevation in the mangrove areas are above an elevation of 0.8 ft NGVD. This elevation was determined from surveyed information in the mangrove areas. The portable pump locations are indicated on the plans. Detailed plan and profile drawings of the portable pumps and pipes are shown on Sheets 5 and 6 of 7. Redirecting the peak flows during the rainy season are part of a larger program to stop expansion of the mangrove die-off areas and eventually reverse the process to restore the dead mangrove areas. Other actions identified by the Task Force have been permitted by FDEP and South Florida Water Management District (SFWMD). They include the reopening of historical drainage channels(FDEP-Ft. Myers), modification of the existing Stormwater Management System for the Pelican Bay development (SFWMD-Ft. Myers), and re-opening of Clam Pass (FDEP-Tallahassee). • 6/4i 6-OIO)C019.©WV 1-0103-081-01•EDOS Agenda Item#5h-1 Page 3 of 3 2• . s .e . t ! t ' 4rte .r • , ft L As stated above,the intent of the project is to assist in the restoration of the Upper Clam Bay mangrove system.

Excessive nutrient supply can stimulate the growth of nuisance plants, creating, on occasion, algal blooms. Algal blooms can reduce water clarity, which is essential for the continued persistence of seagrass meadows, which provide food and shelter for the majority of recreationally and commercially important species of fish and invertebrates (such as crabs and shrimp). Once algal blooms die-off, their decomposition can reduce levels of dissolved oxygen, which is essential to most forms of aquatic life. Successful management of coastal waterbodies thus requires the collection, analysis and interpretation of results from water quality monitoring programs, including data related to nutrient supply. In 2012, the United States Environmental Protection Agency formally adopted nutrient concentration criteria for Clam Bay, as produced for Collier County, and subsequently approved by the Florida Department of Environmental Protection (FDEP). The nutrient criteria for Clam Bay are termed Site Specific Alternative Criteria (SSAC) and they are listed in Florida Administrative Code (FAC) 62-302.531. The SSAC for Clam Bay was derived based upon a relationship between salinity and nutrients that was initially established at one of FDEP's "reference sites" in Estero Bay. The need to take into account salinity was based upon the finding that nutrient concentrations in estuaries and tidal rivers vary not only as a function of the amount of nutrients entering coastal waters, but also as a function of the amount of tidal influence. For example, even in "pristine" estuaries with little to no human impacts, nutrient concentrations are lowest on high tides, and in areas close to passes, and during dry periods with little rainfall-generated stormwater runoff. Even in pristine locations, nutrient concentrations increase away from passes, and on lower tides, and during wet seasons, wet years, or even during shorter time periods of rainfall-generated runoff. Therefore, a single nutrient concentration criterion does not make much sense, if water quality data from even Agenda Item#7c Page 2 of 9 pristine locations could potentially pass or fail proposed criteria simply as a function of location, tidal stage or antecedent rainfall. The SSAC for Clam Bay therefore considers the concentration of nutrients, while also taking into account the salinity, such that a finding of elevated nutrients in combination with higher salinities is considered more problematic than elevated nutrients in combination with lower salinities. As such, the relationship between nutrients and salinity is determined as part of the process to determine if the waters of Clam Bay are "impaired" or not. Also, the frequency with which values exceed NNC criteria is taken into account when determining the appropriate management response, as is the amount of time over which an exceedance has occurred. For example, if nutrient concentrations were to exceed NNC criteria by a relatively small percentage, and if such an exceedance was to only last a short period of time, the appropriate management response would be different than if water quality was to exceed criteria to a larger extent, and if the condition of exceedance was to have lasted for a greater period of time. Therefore, the management response associated with any impairment determination is proportional, and based upon both the magnitude and duration of any exceedances. Based on prior work conducted in Clam Bay, it was found that the amount of floating microscopic algae (i.e., phytoplankton) in the bay was likely stimulated by both Total Nitrogen (TN) and Total Phosphorous (TP). Consequently, the amount of both TN and TP in Clam Bay is used to determine the degree of nutrient enrichment of Clam Bay's waters. As outlined in FAC 62-302.531, the water quality status of waterbodies is to be determined on an annual basis, preferably within a calendar year. For this report, the data collection effort comprised 12 months of effort, but the 12 months did not fall within a single calendar year. Nonetheless, the compilation of results and the interpretation of results presented in this report should be fully consistent with that which would have occurred if the full 12 months of data had been collected in a single calendar year. As outlined in FAC 62-302.531, for each year, each individual TN and TP value collected within Clam Bay is compared to an "upper boundary" of the expected relationship between those two variables and salinty, which was originally informed by the water quality data from an FDEP-designated reference water body. The formal name of the upper boundary condition is the "90th percentile prediction limit" which was originally derived for the relationship between nutrient concentrations and salinity in Clam Bay, and which is based on the determination by FDEP that Clam Bay's water (in 2012) were sufficient to protect its biological integrity. In other words, a TN or TP concentration higher than the 90'th percentile prediction limit is a nutrient concentration higher than at least 90 percent of the values that would be expected, after taking into account the salinity value at the time that the water quality sample was collected. The number of occasions where a nutrient concentration is higher than the 90th percentile prediction limit is quantified for each year, and an annual percent exceedance is then calculated. To be consistent with methods currently used by FDEP, if more than 13 percent of TN or TP concentrations exceed the 90th percentile prediction limit (for a given year) then the year as a whole is classified as one where water quality is out of compliance with the existing criteria. If fewer than 13 percent of the values exceed the 90th percentile prediction limit, then Agenda Item#7c Page 3 of 9 water quality is not considered to be out of compliance. If more than 15 percent of TN or TP values exceed the 90th percentile prediction limit, then the degree of impairment is determined (as per FDEP guidance) to be more problematic than if only 13 percent of values exceeded the established criteria. The screening of water quality data against the adopted NNC criteria is performed as outlined in Figure 1, where different outcomes are given different scores, depending on the frequency of impairment, as well as the duration that the impairment has lasted. As this report summarizes only one year of results, the duration of impairment is not known, but it is assumed (for purposes of this report) to be a single year. Figure 1.

Outcome 0 Outcome 1 Outcome 2 Outcome 3 Agenda Item#7c Page 4 of 9 As a final step, the appropriate management response to water quality within a given year is then identified based on the results from Figure 2. For example, if water quality data suggest that TN and TP concentrations are sufficiently elevated, then it is important to determine if the ecological health of Clam Bay appears to be adversely impacted by those nutrient concentrations.. As a test of the impact of potential nutrient enrichment, water quality data would be tested to determine if phytoplankton levels are perhaps higher, or dissolved oxygen levels lower, based on elevated nutrient concentrations (Figure 3).

With this information as background, the rest of this report will focus on the analysis of water quality data collected during the period of November 2015 to October 2016. Data Analysis The analysis conducted below was used to assess the water quality status of Clam Bay during the months of November 2015 to October 2016. While the period of analysis was not from a single calendar year, it does encompass twelve consecutive months of data collection. Water quality data from Clam Bay and its watershed were provided by Turrell, Hall and Associates, Inc. Agenda Item#7c Page 5 of 9 For comparison with the FDEP adopted SSAC for Clam Bay, as listed within FAC. 62-302-532 -1-j. The water quality data set provided by Turrell, Hall and Associates was analyzed based on the following: "No more than 10 percent of the individual Total Phosphorus (TP) or Total Nitrogen (TN) measurements shall exceed the respective TP Upper Limit or TN Upper Limit." The Upper Limits for TP and TN concentrations noted above are derived based on Equations 1 and 2, respectively: Equation 1: TP Upper Limit (mg/L)= e(-1.06256-0.0o00328465`Conductivity(Ns)) Equation 2: TN Upper Limit (mg/L)= 2.3601 — 0.0000268325*Conductivity(PS) The nutrient dataset examined was supplemented with in situ water quality data (e.g., temperature, dissolved oxygen, pH, conductivity, and salinity) retrieved from the chain of custody forms for each sampling event. TN and TP concentrations were compared to the derived upper limit thresholds to quantify the presence or absence of elevated concentrations of TP and/or TN, with results listed in (Appendix A). Over the period analyzed (November 2015 to October 2016), a total of four (4) ambient water quality values for TN exceeded the respective TN Upper Limit, for an exceedance frequency of approximately 4 percent. In comparison, 20 of the 107 TP measurements (approximately 19 percent) exceeded their respective TP Upper Limit. Based on these results, the frequency of exceedance would not be high enough for the waters of Clam Bay to be determined to be impaired for TN, but those same waters would be determined to be impaired for TP. Should the TP exceedance lasts only this single year, the outcome from the flowchart shown in Figure 1 would that of a score of"2" for TP and a score of"0-" for TN. With one year's worth of data, the combination of outcome "2" for TP and outcome "0" for TN would result in a "yellow" management response, as illustrated in Figure 2. Since the TP exceedances were greater than 15 percent, then the "yellow" management response would be the outcome for this first year's data collection effort. Consequently, the following additional data investigations were conducted: • Determining the relationship, if any, between TP and chlorophyll-a • Determining the relationship, if any, between TP and dissolved oxygen • Determining the relationship, if any, between chlorophyll-a and water clarity Depending upon the findings of the analyses listed above, management implications would be developed, which could range from recommendations up to and including the need to determine the basis for a potential adverse impact on water quality. A review of the annual dataset indicated a direct relationship between TP and chlorophyll- concentrations (Figure 5) as well as an inverse relationship between TP and dissolved oxygen (Figure 6). Water clarity data were not included in the reviewed data sheets, and so were not Agenda Item#7c Page 6 of 9 reviewed to determine if there was a correlation between chlorophyll-a concentrations and water clarity. As such, we were unable to evaluate the influence of chlorophyll-a on water clarity in Clam Bay. Figure 4.

Outfall TN and TP concentrations were compared to the median and 90th percentile DPV values to determine if elevated concentrations were found at those locations (Appendix B). The median DPV quantity represents a value that would be expected to be exceeded approximately 50 percent of the time, while the 90th percentile value represents a concentration sufficiently high that only 10 percent of values would be expected to be higher. Using this approach, the amount of TN or TP in the water column at stations sampled in the Clam Bay watershed can be compared to criteria that are meant to be protective of the open waters of Clam Bay. The TN and TP concentrations in DPV estimates will be higher than concentrations in the open waters of Clam Bay, as the influence of the more saline and lower nutrient content waters of the Gulf of Mexico would not yet have diluted the higher nutrient concentrations found in freshwater inflows from the watershed. The median and 90th percentile DPVs for TN are 1.31 and 1.8 mg/L, respectively. The median and 90th percentile DPVs for TP are 0.1 and .25 mg/L, respectively. For data collected at the outfall monitoring sites, 58 and 20 percent of the TN concentrations exceeded the median and 90th percentile DPV values for TN, respectively (Table 1). For those same outfall monitoring sties, 68 and 22percent of the TP concentrations exceeded the median and 90th percentile DPV values, respectively (Table 1). Table 1.

The abundance of phosphorous positively correlate with chlorophyll- a concentrations in Clam Bay, which suggests that the availability of phosphorous influences the amount of phytoplankton in Clam Bay. Also, increased phosphorous concentrations are inversely correlated with levels of dissolved oxygen in Clam Bay. Data collected from the outfall monitoring stations suggest that nitrogen concentrations are somewhat elevated, but that most of the elevated concentrations of nitrogen are from the highest values recorded, rather than there being a "typical" condition of elevated nitrogen enrichment. For phosphorous, elevated concentrations are found both in typical conditions and also amongst the highest concentrations, compared to earlier time periods. These results suggest that the watershed and open waters of Clam Bay should continue to be monitored on a regular basis, as there is the possibility that phosphorous loads, in particular, could become problematic to the water quality and ecosystem health of Clam Bay, particularly if phosphorous concentrations increase over time. Additionally, as nutrient concentrations vary as a function of the balance between stormwater runoff and mixing with the waters of the Gulf of Mexico, the tidal prism for the Clam Bay system should be maintained such that it continues to allow for sufficient tidal exchange of the waters of Upper, Inner and Outer Clam Bay.

Agenda Item#7ei Page 1 of 1 CLAM BA YNRPA MANAGEMENT PLAN Pelican Bay Services Division October 2014 Ver. 6.5 FDEP did determine that the Clam Bay system was impaired for copper and placed the Clam Bay system on the Everglades West Coast verified list for copper with medium TMDL priority(5 to 10 years for TMDL development). TMDL(Total Maximum Daily Load)is defined by the FDEP as the maximum amount of a given pollutant that a surface water can absorb and still meet water quality standards. Subsequent copper testing undertaken by PBSD has also shown periodic elevated levels of copper within the Clam Bay Class II waters. Beginning in 2015 PBSD's water quality monitoring program in the Clam Bay NRPA system will employ the sampling program used to establish the SSAC. Sampling locations within the open waters of the NRPA will be increased and relocated from the 5 historical locations to the 9 locations subsequently established. These 9 locations are shown on Figure 18. Sampling will continue to be collected on a monthly basis. The suite of parameters collected and analyzed from the water samples will also be amended as outlined below in order to provide the information necessary to more easily interpret the compliance with the newly established SSAC. • Field pH • Field Temperature • Field Salinity • Field Specific Conductance • Field Dissolved Oxygen(mg/1) • Field Dissolved Oxygen(% Saturation) • Ammonia • Chlorophyll a • Copper • Nitrate-Nitrite(NO3-NO2) • Nitrite(NO2) • Total Nitrogen • Orthophosphate(0PO4) • Pheophytin • Total Phosphorous The PBSD is developing an upland stormwater and nutrient management program that builds upon the Nutrient Management Plan previously completed for the Pelican Bay Foundation(Turrell,2013). The Foundation Plan and ongoing nutrient management efforts in process by the PBSD are designed to reduce nutrient and copper inputs into the stormwater system. Once completed,the PBSD program will be reviewed by the FDEP. If copper concentrations in the NRPA are reduced as a result of the implementation of the program,the FDEP could consider removal of the Clam Bay NRPA system from the impaired list. The information garnered from the PBSD's nutrient monitoring and management activities will be important in guiding future decision making associated with water quality concerns in the Clam Bay NRPA. PBSD will work closely with the Pelican Bay Foundation and adjacent communities on nutrient management issues to coordinate and share information that may be integrated into management decisions and activities undertaken through this Management Plan. 34 Agenda Item#7c-1 Page 1 of 1 CLAM BAYNRPA MANAGEMENT PLAN Pelican Bay Services Division October 2014 Ver. 6.5 �'. �� f -,‘,..
