Shark River Slough. The Consent Decree of 1995 specified that interim and long-term total phosphorus concentration limits for discharges into the Everglades National Park (ENP) (Figure 3) through Shark River Slough be met by October 1, 2003, and December 31, 2006, respectively. Only the total phosphorus concentrations for the water year ending September 30 are evaluated for compliance with the Consent Decree limits. It was also specified that the total phosphorus concentrations be presented as 12-month moving flow-weighted means. The long-term total phosphorus concentration limit for inflows to Shark River Slough through structures S12A, S12B, S12C, S12D and S333 represents the concentrations delivered during the Outstanding Florida Waters baseline period of March 1, 1978 to March 1, 1979, and is adjusted for variations in flow. Inflow concentrations of total phosphorus through Shark River Slough are compared to the interim and long-term limits at the end of each water year (October 1st through September 30th) from 1991 to 2005 (Figure 4). The 12-month moving flow-weighted mean total phosphorus concentration ending September 2005 was 9.4 ppb. Corresponding interim and long- term limits were 9.4 and 7.6 ppb, respectively. The Consent Decree stipulates that the percent of flow-weighted mean total phosphorus concentrations greater than 10 ppb from each sampling event in any 12- month period must not exceed a guideline value based on flow into Shark River Slough for the same 12-month period. For the 12-month periods ending July, August and September 2005, the observed percentage of flow-weighted mean total phosphorus concentrations greater than 10 ppb were 55.0, 47.6 and 42.9 percent, respectively. The observed percentage of flow-weighted mean total phosphorus concentrations greater than 10 ppb were less than the guideline for the entire period March 2004 to April 2005 and higher than the guidelines from May to September 2005 (Table 2).

Inflow concentrations of total phosphorus TP through Shark River Slough are compared to the interim and long-term limits at the end of each water year (October 1st through September 30th) from 1991 to 2005 2006 (Figure 4). The 12-month moving flow-weighted mean total phosphorus TP concentration ending September 2005 2006 was 9.4 8.7 ppb. Corresponding interim and long- long-term limits were 9.4 10.3 and 7.6 8.8 ppb, respectively. 8.7 ppb, respectively. The interim limits were 9.4, 9.9 and 10.3 ppb, respectively.

Shark River Slough. The Consent Decree of 1995 specified that interim and long-term total phosphorus concentration limits for discharges into the Everglades National Park (ENP) (Figure 3) through Shark River Slough be met by October 1, 2003, and December 31, 2006, respectively. Only the total phosphorus concentrations for The limits apply to the water year ending September 30 are evaluated for compliance with the Consent Decree limits. It was also specified that the total phosphorus concentrations be presented as 12-month moving flow-weighted means30. The long-term total phosphorus concentration limit for inflows to Shark River Slough through structures S12A, S12B, S12C, S12D and S333 represents the concentrations delivered during the Outstanding Florida Waters baseline period of March 1, 1978 to March 1, 1979, and is adjusted for variations in flow. In addition, it is required that phosphorus concentrations be presented as 12-month moving flow-weighted means. Inflow concentrations of total phosphorus through Shark River Slough are compared to the interim and long-term limits at the end of each water year (October 1st through September 30th) from 1991 to 2005 2001 (Figure 42a). The 12-month moving flow-weighted mean total phosphorus concentration ending September 2005 2001 was 9.4 15.0 ppb. Corresponding interim and long- long-term limits were 9.4 12.2 and 7.6 10.8 ppb, respectively. This was the second consecutive year that both limits were exceeded for the water year ending in September. Both the 2000 and 2001 water years were very dry, resulting in lower volumes of flow with higher total phosphorus concentrations entering the Park than those observed in wetter years. Analysis of the TP concentrations in Shark River Slough by the TOC is continuing. Preliminary evaluation suggests that drought conditions, implementation of phosphorus controls and local water management are contributing factors to the ambient concentrations. The Consent Decree stipulates that the percent of flow-weighted mean total phosphorus concentrations greater than 10 ppb from each sampling event in any 12- 12-month period must not exceed a guideline value based on flow into Shark River Slough for the same 12-month period. For the 12-month periods ending JulyApril, August May and September 2005June 2002, the observed percentage percent of flow-weighted mean total phosphorus concentrations greater than 10 ppb were 55.040.9, 47.6 43.5 and 42.9 percent40.9, respectively. The These observed percentage of flow-weighted mean total phosphorus concentrations greater than 10 ppb values were all less than the guideline for the entire period March 2004 to April 2005 and higher than the their respective guidelines from May to September 2005 (Table 2). The individual sampling events and the 12-month moving average are presented in Figure 52b.

Shark River Slough. The Consent Decree of 1995 specified that interim and long-term total phosphorus concentration limits for discharges into the Everglades National Park (ENP) (Figure 3) through Shark River Slough be met by October 1, 2003, and December 31, 2006, respectively. Only the total phosphorus concentrations for The limits apply to the water year ending September 30 are evaluated for compliance with the Consent Decree limits. It was also specified that the total phosphorus concentrations be presented as 12-month moving flow-weighted means30. The long-term total phosphorus concentration limit for inflows to Shark River Slough through structures S12A, S12B, S12C, S12D and S333 represents the concentrations delivered during the Outstanding Florida Waters baseline period of March 1, 1978 to March 1, 1979, and is adjusted for variations in flow. In addition, it is required that phosphorus concentrations be presented as 12-month moving flow-weighted means. Inflow concentrations of total phosphorus through Shark River Slough are compared to the interim and long-term limits at the end of each water year (October 1st through September 30th) from 1991 to 2005 2002 (Figure 43a). The 12-month moving flow-weighted mean total phosphorus concentration ending September 2005 2002 was 9.4 8.8 ppb. Corresponding interim and long- long-term limits were 9.4 9.6 and 7.6 7.9 ppb, respectively. This was the first year since 1999 that the interim limit was not exceeded for the water year ending on September 30. This return to lower concentrations observed in the mid-1990s corresponds with increasing flow into Shark River Slough. Both the interim and long-term limits have not been met in the same year since 1997. Table 2 presents the moving flow-weighted mean concentrations for each 12- month period beginning in October 2000, as well as the corresponding interim and long-term total phosphorus concentration limits, calculated using the 12-month period flow. For the 12-month periods ending in July, August and September 2002, the flow-weighted mean total phosphorus concentrations were 10.9, 9.1 and 8.8 ppb, respectively. The Consent Decree stipulates that the percent of flow-weighted mean total phosphorus concentrations greater than 10 ppb from each sampling event in any 12- 12-month period must should not exceed a calculated guideline value based on flow into Shark River Slough for the same 12-month period. For the 12-month periods ending July, August and September 20052002, the observed percentage percent of flow-weighted mean total phosphorus concentrations greater than 10 ppb were 55.045.8, 47.6 39.1 and 42.9 percent30.4, respectively. The July observed percentage of flow-weighted mean total phosphorus concentrations was greater than 10 ppb the guideline, but the August and September percentages were less lower than the guideline for the entire period March 2004 to April 2005 and higher than the their respective guidelines from May to September 2005 (Table 2). The individual sampling events and the 12-month moving average averages are presented in Figure 53b.
