Figure 2.30 Big Fishweir Creek (WBID 2280).

• West of Downtown, South of I-10
• Primary Land Use: Residential
• Current TMDL reports: Fecal Coliform with BMAP (2009)
• 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

·       Zinc

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

  • WBID Area: 1.31 sq. miles
  • Beneficial Use: Class III F (Recreational – Freshwater)

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
  • Lead
  • Zinc
  • Cadmium
  • Nickel
  • Total nitrogen
  • Copper

  • Verified Impaired 2016 (final): Iron (2213P2, 2262B med)
  • WBID Area: 22.8 sq. mi.
  • Beneficial Use: Class III F (Recreational – Freshwater)

2.7.7.2. 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 Cedar River WBID 2262 and 2213P2 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.8.

2.7.7.3. Discussion

Water quality data for the Cedar River are shown in Table 2.8. The Cedar River feeds into the Ortega River and thus is not directly a tributary of the St. Johns River. Even so, the Cedar River is tidal in nature, varying in height by ~1 ft over the course of a day (SJRWMD 2010d). Salinity levels, as influenced by tidal movement, are relatively low indicating that the Ortega River buffers the Cedar River significantly from marine water intrusion. Average dissolved oxygen levels were above the WQC over the past three years. Average total phosphorus levels have been near to or higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k). Heavy metal concentrations increased in 2018, with several water samples exceeding the WQC for cadmium and silver.

In 2004, Cedar River was identified as being impaired for both fecal and total coliforms (i.e., levels significantly above 400 CFU/100 mL) and as a result, a TMDL report was finalized in 2006 (Magley 2006b). (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Currently, a Basin Management Action Plan (BMAP) to address this impairment is under development, but the timeframe for its release is currently unknown.

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

2.7.22.2. 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 Ortega River WBID 2213P1 and 2249A (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.23.

2.7.22.3. Discussion

Water quality data for the Ortega River are shown in Table 2.23. Average total phosphorus and dissolved oxygen concentrations were within acceptable limits. Average chlorophyll-a concentrations have remained lower than the WQC, but there was a sharp increase in the average concentration in 2017. Concentrations of metals in the Ortega River had generally decreased from 2015 to 2017, although the concentration of many of the metals shown in Table 2.23 rose in 2018.

No valid fecal coliform measurements were available in STORET between 2013 and 2017, but measurements were reported in WIN in 2018.  The fecal coliform level, averaged over all the sampling sites in the Ortega River, was historically below the WQC of 400 colony-forming-units per 100 mL. The TMDL reports for fecal coliform (Rhew 2009f) and DO/Nutrients (Magley 2009b) published in 2009 referred to WBID 2213P, of which WBID 2213P1 is a subset as a result of changes to the WBID boundaries.

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

2.7.30.2. 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 Wills Branch WBID 2282 (DEP 2014c) shown above. No water quality data for the selected parameters discussed below for Wills Branch were available in STORET for 2015-2017.

2.7.30.3. Discussion

Water quality data for Wills Branch are presented in Table 2.30.  Historically, average total phosphorus, dissolved oxygen and chlorophyll-a concentrations were within acceptable limits, and reported measurements from 2018 continue this trend.

The fecal coliform level, averaged over all the stations in Wills Branch, were historically above the WQC of 400 colony-forming-units (CFU) per 100 mL. As a result, a TMDL for total and fecal coliform was published in 2006 (Wainwright 2006c) for Wills Branch. (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Subsequently, a BMAP for Wills Branch was legally adopted in 2010 (DEP 2010a). 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 20 active, ongoing projects underway by FDOT and JEA to address the BMAP in the Wills Branch watershed (DEP 2017c); two pump station projects were completed by JEA in 2016.  No fecal coliform measurements were reported in STORET from 2013 to 2017, and measurements from 2018 showed elevated fecal coliform levels.

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 Wills Branch are available in previous versions of the River Report.
