  • Between downtown and Jacksonville International Airport (JIA)
  • Primary Land Use: Residential/Forested
  • Current TMDL reports: None
  • 2022 Verified Impairment for Fecal Coliform (2191B)
  • WBID Area: 14.4 sq. mi.
  • Beneficial Use: Class III F/M (2191A – Recreational Freshwater, 2191B – Recreational Marine)

2.7.5.2. Data sources

Data were historically downloaded from the FL STORET website (DEP 2010f), with recent data downloaded from WIN WAVES (DEP 2022f). Data were filtered based on the stations in the Broward River WBID 2191A/B (DEP 2023b) shown above. The filtered dataset reflects water column concentrations and was used to generate Table 2.10.

2.7.5.3. Discussion

Water quality data for the Broward River are shown in Table 2.10. Little water quality data is available for the Broward River compared to other tributaries. Historically, average phosphorus levels were higher than the 2010 updated WQC (DEP 2015c; DEP 2016d; DEP 2016i).   Historical maximum fecal coliform level at times exceeded the WQC, and as a result, the marine reach (2191B) was listed as impaired for fecal coliform. FDEP considers the Broward River a low priority for the development of a TMDL to address Fecal Coliform levels (DEP 2016d). Average fecal indicator bacteria levels did not usually exceed the WQC in 2022, although there are few samples to base this assessment on.  The Broward River was identified as being impaired for mercury, based on elevated levels of mercury in fish tissue; however, it was delisted (DEP 2016f) as it has been addressed by the statewide mercury TMDL (DEP 2013c).

The freshwater segment of the Broward River was added to the FDEP study list for dissolved oxygen (DEP 2020f). The freshwater segment is considered impaired for dissolved oxygen based on the number of exceedances for the sample size, but the causative pollutant has not yet been identified.

No recent measurements were available in WIN between 2020 and 2022 for both freshwater and marine reaches (WBID 2191A, 2191B) for the following parameters: Total Nitrogen, Total Phosphorus, Chlorophyll-a, Arsenic, Cadmium, Copper, Iron, Lead, Nickel, Silver, Zinc, Turbidity.

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

2.7.29.2. Data sources

Result data were historically downloaded from the FL STORET website (DEP 2010f), with recent data downloaded from WIN WAVES (DEP 2022f). Data were filtered based on the stations in the Trout River WBIDs 2203 (freshwater), 2203A (marine), 2203B (marine), and 2223 (freshwater) (DEP 2023b) shown above. The filtered dataset reflects water column concentrations and was used to generate2Table 2.31.

2.7.29.3. Discussion

Water quality data for the Trout River are shown in Table 2.32. Historically, overall (all WBIDs) average phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016d; DEP 2016i). Average total phosphorus concentrations from 2020-2021 were near or exceeded the WQC, with concentrations exceeding the WQC in the freshwater reach (2203, 2223) in 2022. Average total nitrogen concentrations also exceeded the WQC in the freshwater reach in 2022.  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), with a 30% reduction in total nitrogen and 70% reduction in total phosphorus from contributing sources. Dissolved oxygen concentrations were within acceptable limits in both the freshwater and marine reaches of the Trout River tributary, although there were several individual samples in the marine reach that exceeded WQC. Average chlorophyll-a levels in the marine reach of the Trout River (2203A/B) exceeded the WQC in 2021 (no measurements reported in 2020 or 2022).  From 2020-2022, fewer nutrient measurements were reported in WIN, making it difficult to draw accurate conclusions about the condition of the tributary. The Trout River (lower reach) was identified as being impaired for mercury based on elevated levels of mercury in fish tissue; however, Trout River was delisted (DEP 2016f), as it has been addressed by the statewide mercury TMDL (DEP 2013c). In 2020, the Trout River (2223) was identified as being Impaired for lead based on the number of exceedances for the sample size (DEP 2020g; DEP 2022). FDEP has assigned a low priority for the development of a TMDL to address elevated lead concentrations.

The historical fecal coliform level has been higher than the WQC.  A TMDL for fecal coliform was published in 2009 (Wainwright and Hallas 2009c) for WBIDs 2203 and 2203A, with a 60% reduction in contributing sources. (Note: the data analyses in the TMDL are based on different criteria than those used in this report). Subsequently, a BMAP for the Trout River (DEP 2010a) was legally adopted in August 2010. 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 2017b). 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). Average fecal indicator bacteria levels remain above or near the WQC 2020-2022 in the freshwater reach (E. coli) and saltwater reach (Enterococci).  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 2017b). In 2018, FDEP piloted microbial source tracking strategies in selected impaired waterbodies. They found that the strategies used could be used to narrow down areas suspected of containing sources that actively contribute fecal indicating bacteria to water in order to identify and remediate them, but this work is resource-intensive. WBID 2203B of the Trout River was suspected to have sources of untreated human waste present, and the source of fecal coliform in WBIDs 2203 and 2203A were unknown (DEP 2019a).  In 2020, the upper reach of the Trout River (WBID 2223) was verified as Impaired for fecal coliform (E. coli) based on the number of exceedances for the sample size, and anthropogenic sources of bacteria have been confirmed using genetic marker analysis and chemical tracer data (DEP 2020g; DEP 2022).  The middle reach of the Trout River middle segment (WBID 2203B) was added to FDEP’s study list in 2020 to monitor the response of fecal coliform (enterococci) concentrations to ongoing restoration activities taking place as part of the existing BMAP (DEP 2020f). Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.3.

No recent measurements were available in WIN between 2020 and 2022 for the marine reach (2203A, 2203B) for the following parameters: Arsenic, Cadmium, Copper, Iron, Lead, Nickel, Silver, Zinc, Turbidity.
