• Verified Impaired 2016 (final):
Iron (2280A med)
• WBID Area: 3.7 sq. mi.
• Beneficial Use: Class III F (Recreational – Freshwater)

2.7.3.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in Big Fishweir Creek WBID 2280, 2280A (freshwater), and 2280B (saltwater/marine) (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.4.

2.7.3.3. Discussion

Water quality data for Big Fishweir Creek are shown in Table 2.4. Big Fishweir Creek has been listed as Impaired for high levels of iron (DEP 2016j).  A TMDL report (Wainwright and Hallas 2009a) was released in 2009 to address Fecal coliform, and Big Fishweir Creek has been delisted from the Impaired Waters list (DEP 2016h) (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Subsequently, a BMAP to address this issue was legally adopted (DEP 2009b). Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

The last Annual Progress Report for this BMAP was published in 2016 and listed 16 active, ongoing projects underway by FDOT and JEA to address the BMAP in the Big Fishweir Creek watershed (DEP 2017c). FDEP reported improvement in the frequency of fecal coliform exceedances in the marine segment of Big Fishweir Creek, but recent fecal coliform measurements continue to show significant fecal coliform concentrations.

No recent measurements were available in WIN or STORET between 2016 and 2018 for the following parameters:

·       Arsenic

·       Cadmium

·       Copper

·       Lead

·       Nickel

·       Silver

2.7.6.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in Butcher Pen Creek WBID 2322 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.5.

2.7.6.3. Discussion

Water quality data for Butcher Pen Creek are shown in Table 2.7. Historical phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k), but recent phosphorus data are lacking in STORET. The average fecal coliform level exceeded the WQC of 400 colony-forming-units per 100 mL in each of the last three years (Table 2.7). As a result, a TMDL report was published in 2005 (Wainwright 2005a) to address this issue. Subsequently, a BMAP to address this issue was legally adopted (DEP 2009b). The last Annual Progress Report for this BMAP was published in 2016 and listed 16 active, ongoing projects underway by FDOT and JEA to address the BMAP in the Butcher Pen Creek watershed (DEP 2017c). Despite these efforts, fecal coliform levels have remained high over the past three years. Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

Butcher Pen Creek was previously impaired for chlorophyll-a, but annual levels have fallen below the nutrient threshold, and it has been delisted for chlorophyll-a (DEP 2016h).

No recent measurements were available in WIN or STORET between 2016 and 2018 for the following parameters:

  • Arsenic

2.7.15.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Hogan Creek WBID 2252 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.16.

2.7.15.3. Discussion

Water quality data for Hogan Creek are shown in Table 2.16.  No data were available in STORET for 2016, only two measurements were performed in 2017, and no metal data were available for 2018, limiting the utility of these measurements in assessing the water quality in Hogan Creek.  Historical average phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k), and the average phosphorus level in 2017 was near the WQC. Chlorophyll-a and dissolved oxygen concentrations appear to be within acceptable limits.

A TMDL for fecal coliform in Hogan Creek was finalized in 2006 (Wainwright 2006d). (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Subsequently, a BMAP for Hogan Creek was legally adopted in December 2009 (DEP 2009b). Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2. The last Annual Progress Report for this BMAP was published in 2016 and listed 21 active, ongoing projects underway by FDOT and JEA and 2 projects completed in 2016 (pump station rebuilding by JEA, flood improvements by COJ)  to address the BMAP in the Hogan Creek watershed (DEP 2017c). FDEP reported improvement in the frequency of fecal coliform exceedances in the freshwater segment of Hogan Creek, but the last fecal coliform measurements in Hogan Creek available in STORET prior to 2018 date back mainly to 2008, with a single measurement in 2011.  Recent measurements suggest ongoing issues with fecal coliform concentrations.

In 2012, COJ worked with the US Army Corps of Engineers to investigate the potential to remediate and restore the aquatic ecosystem through removal of accumulated sediment, removal of exotic vegetation, and creation of wetland habitats.  Fourteen sites within the Hogan Creek watershed were under consideration for restoration, but sampling of ten of these sites in 2003 revealed hazardous, toxic, and radioactive waste contamination in both the creek itself and the adjacent lands.  Ash deposits dating back to the early 20th century can be found in the Hogan Creek watershed, and these are known sources of hazardous and toxic waste. Removal of these hazardous materials would prevent them from leaching into the creek and being taken up by plants and animals, but this (potentially extensive) work would need to be performed and paid for by either COJ or an organization contracted by COJ to do so.  The USACE elected not to proceed with any work or action until these hazardous materials were removed, after which the project could be reconsidered (USACE 2012a).

  • WBID Area: 5.34 sq. mi.
  • Beneficial Use: Class III F (Recreational – Freshwater)

2.7.18.2. Data sources

Result data was downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in McCoy Creek WBID 2257 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.19.

2.7.18.3. Discussion

Water quality data for McCoy Creek are shown in Table 2.19. The fecal coliform level, averaged over all the stations in McCoy Creek, was historically above the WQC of 400 colony-forming-units (CFU) per 100 mL. Thus, a TMDL for fecal coliform was published in 2009 (Rich-Zeisler and Kingon 2009). (Note: the data analysis in the TMDL is based on different criteria than that used in this report). Subsequently, a BMAP for McCoy Creek was legally adopted in 2010 (DEP 2010a). The last Annual Progress Report for this BMAP was published in 2016 and listed 20 active, ongoing projects underway by COJ, FDOT, and JEA and one completed project in 2016 (wet detention pond by COJ) to address the BMAP in the McCoy Creek watershed (DEP 2017c). Measurements from the past three years suggest that progress is being made.  Average fecal coliform concentrations remain above the WQC, although the average has decreased over the past three years. Roughly half of the fecal coliform measurements exceed the WQC. Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

Average dissolved oxygen (DO) levels are above the SSAC of 4.0 mg/L for DO in the mainstem and tributaries (DEP 2014b), and the average DO concentration increased in 2018 following a three-year period of decreases.

While ample data are available for dissolved oxygen, fecal coliform, and turbidity levels in McCoy Creek, limited data can be found in STORET for phosphorus and chlorophyll-a prior to 2018.  No recent measurements were available in WIN or STORET between 2016 and 2018 for the following parameters:

  • Arsenic
  • Lead
  • Zinc
  • Cadmium
  • Nickel
  • Copper
  • Silver

Historical water quality data for these parameters in McCoy Creek are available in previous versions of the River Report.

2.7.20.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Moncrief Creek WBID 2228 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.21.

2.7.20.3. Discussion

Water quality data for Moncrief Creek are shown in Table 2.21. Historical average phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k), and the average phosphorus levels have remained slightly above the WQC over the past three years. Dissolved oxygen concentrations were within acceptable limits.  Average chlorophyll-a concentrations were higher in 2017 and 2018.

A TMDL report for fecal coliform was published for Moncrief Creek in 2006 (Wainwright 2006b). (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Subsequently, a BMAP for Moncrief Creek (DEP 2010a) was released in August 2010. It describes sources of fecal coliform in the watershed, and completed and ongoing activities conducted by state and local agencies that are anticipated to reduce fecal coliform loading in the tributary. Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

In the 2016 Annual Progress Report, 59% of Moncrief Creek fecal coliform measurements over a 7.5 year period ending June 30, 2016 exceeded the water quality criterion (400 CFU/100 mL) (DEP 2017c). While Moncrief Creek remains impaired for fecal coliform, the size of the exceedances has decreased since implementation of the BMAP; the median exceedance has decreased from 2,600 CFU/100 mL in the TMDL report to 1,300 CFU/100 mL in the first phase of the BMAP (2010-2014). (DEP 2016b).  Fecal coliform measurements from the past three years show improvements in the average fecal coliform concentration as well as in the frequency of measurements that exceed the fecal coliform WQC.  Average fecal coliform concentrations continued to decrease from 2016 to 2018, as did the percentage of measurements that exceeded the WQC. There were 28 projects either planned or currently underway in 2016 by COJ, JEA, and FDOT to address the BMAP in the Moncrief Creek watershed (DEP 2017c).

Moncrief Creek has been identified as impaired for copper and iron (DEP 2014e), but it has been delisted for lead (DEP 2016h). It was identified as being impaired for mercury, based on elevated levels of mercury in fish tissue; however, this is being delisted (DEP 2015a) as it has been addressed by the statewide mercury TMDL (DEP 2013c).  Concentrations of the heavy metals presented in Table 2.21 all decreased in 2018, while these same metal concentrations increased in some of the other tributaries.

COJ has chosen Moncrief Creek as a focus watershed to monitor progress in the reduction of pollution from stormwater flows.  Stormwater is the main source of the headwaters of Moncrief Creek, and there were 22 stormwater treatment ponds in the Moncrief Creek watershed in 2017.  COJ plans to sample Moncrief Creek quarterly with respect to its effectiveness in stormwater treatment pollution reduction (COJ 2017).

Historical water quality data for Moncrief Creek are available in previous versions of the River Report.

2.7.25.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Ribault River WBID 2224 (DEP 2014c) shown above. No water quality data for the selected parameters discussed below for the Ribault River were available in STORET for 2015-2017.

2.7.25.3. Discussion

Water quality data for the Ribault River are presented in Table 2.26. No water quality data were available in STORET for the Ribault River between 2012 and 2017, and the last measurements of metals date back to 2007.  The average total phosphorus concentration is near the WQC.  The Ribault River is located in a highly residential area and has historically been a contributor to elevated levels of phosphorus found in the tributary. High levels of chlorophyll-a were measured previously and again in 2018 (although the average did not exceed the WQC), but Ribault River has not been designated impaired (DEP 2016h). The Ribault River has been added to the verified impaired list for iron (DEP 2016j).

Historical fecal coliform levels, averaged over all the sampling sites in the Ribault River, were elevated. A TMDL report for fecal coliform in the Ribault River was published in 2006 (Wainwright 2006a), and a BMAP is under development. (Note: the data analyses in the TMDL are based on different criteria than that used in this report).  In 2014, the City of Jacksonville implemented a monitoring program for the Ribault River as part of a bacteria pollution control plan in concert with efforts related to stormwater management (COJ 2017).  Fecal coliform measurements from 2018 show elevated levels, with over half of the measurements exceeding the WQC.

No recent measurements were available in WIN or STORET between 2016 and 2018 for the following parameters:

  • Arsenic
  • Cadmium
  • Copper
  • Lead
  • Nickel
  • Silver
  • Zinc

Historical water quality data for these parameters in the Ribault River are available in previous versions of the River Report.

Figure 2.64 The Trout River Tributary (WBIDs 2203/2203A/2223).
  • North of downtown Jacksonville
  • Primary Land Use: Residential/Wetland Current TMDL reports: Fecal coliform with BMAP (2010) DO/Nutrients (2203B), Mercury
  • Verified Impaired 2016 (final): Chlorophyll-a (2203A, med)
  • Beneficial Use: Class III M/F (Marine 2203A, Freshwater 2203/2233)

2.7.29.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Trout River WBIDs 2203/2203A/2203B/2223 (DEP 2014c) shown above. The filtered dataset was used to Table 2.29.

2.7.29.3. Discussion

Water quality data for the Trout River are shown in Table 2.29. Historically, overall (all WBIDs) average phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k).  No phosphorus data were available in STORET from 2014 to 2016, and the average phosphorus concentration in both 2017 and 2018 were at or near the WQC, with a number of measurements in 2018 exceeding the WQC.  Dissolved oxygen concentrations were within acceptable limits and improved in 2018. Nutrient levels have been found to be, on average, higher than the WQC for WBID 2203 and a TMDL report to address this issue was published in 2009 (Magley 2009a). The Trout River has been listed as impaired for chlorophyll-a (DEP 2016j).

The fecal coliform level, averaged over all the stations in the Trout River (Table 2.29), has been higher than the WQC of 400 colony-forming-units (CFU) per 100 mL.  A TMDL for fecal coliform was published in 2009 (Wainwright and Hallas 2009c) for WBIDs 2203 and 2203A in the Trout River. (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Subsequently, a BMAP for the Trout River (DEP 2010a) was legally adopted in August 2010. It describes sources of fecal coliform in the watershed, and completed and ongoing activities conducted by state and local agencies that are anticipated to reduce fecal coliform loading in the tributary. The BMAP describes two WBIDS: the middle Trout River (2203), and the lower Trout River (2203A). Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

Annual Progress Reports for this BMAP were published annually between 2011 and 2016, listing repairs, inspections, evaluations, and other improvements conducted by JEA, the Duval County Health Department, COJ, and FDOT. In the 2016 Annual Progress Report, 32% of lower Trout River fecal coliform measurements over a 7.5 year period ending June 30, 2016 exceeded the water quality criterion (400 CFU/100 mL) (DEP 2017c). While the lower Trout River remains impaired for fecal coliform, the size of the exceedances has decreased since implementation of the BMAP; the median exceedance decreased from 1,000 CFU/100 mL in the TMDL report to 721 CFU/100 mL in the first phase of the BMAP (2010-2014) (DEP 2016b). However, fecal coliform concentrations over the past three years have remained high (although limited sampling was performed in 2017). As of 2016, there were 42 projects either planned or currently underway by COJ, JEA, and FDOT to address the BMAP in the Trout River watershed (DEP 2017c).

The Trout River (lower reach) was identified as being impaired for mercury based on elevated levels of mercury in fish tissue; however, this is being delisted (DEP 2016h), as it has been addressed by the statewide mercury TMDL (DEP 2013c). Chlorophyll-a has been added to the verified impaired list (DEP 2016j), although reported measurements in 2018 were all below the WQC.

Historical water quality data for the Trout River are available in previous versions of the River Report.
