| TMDL End Point: | THE TMDLS FOR IMPAIRED WATERBODIES IN THE WATTS BAR WATERSHED WERE DEVELOPED USING THE LOAD DURATION CURVE METHODOLOGY TO ASSURE COMPLIANCE WITH THE E. COLI 126 COUNTS/100 ML GEOMETRIC MEAN AND 941 COUNTS/100 ML MAXIMUM STANDARDS WHILE ALSO INCORPORATING THE FECAL COLIFORM 200 COUNTS/100 ML GEOMETRIC MEAN AND 1,000 COUNTS/100 ML MAXIMUM CONCENTRATION AS SURROGATES. A DURATION CURVE IS A CUMULATIVE FREQUENCY GRAPH THAT REPRESENTS THE PERCENTAGE OF TIME DURING WHICH THE VALUE OF A GIVEN PARAMETER IS EQUALED OR EXCEEDED. LOAD DURATION CURVES ARE DEVELOPED FROM FLOW DURATION CURVES AND CAN ILLUSTRATE EXISTING WATER QUALITY CONDITIONS (AS REPRESENTED BY LOADS CALCULATED FROM MONITORING DATA), HOW THESE CONDITIONS COMPARE TO DESIRED TARGETS, AND THE PORTION OF THE WATERBODY FLOW REGIME REPRESENTED BY THESE EXISTING LOADS. LOAD DURATION CURVES WERE USED TO DETERMINE THE LOAD REDUCTIONS REQUIRED TO MEET THE TARGET MAXIMUM CONCENTRATIONS FOR FECAL COLIFORM AND E. COLI (STANDARD - MOS). WHEN SUFFICIENT DATA WERE AVAILABLE, LOAD REDUCTIONS WERE ALSO DETERMINED BASED ON GEOMETRIC MEAN CRITERIA. | |||
