12. LSJR Indicators of Eutrophication Post-TMDL What DoTrends Indicate? Downward trends in N, P (under low flow) and chlorophyll-a, and increase in D.O., concur with TMDL findings and demonstrate effectiveness of nutrient load reduction in improving WQDownward trends in N, P (under low flow) and chlorophyll-a, and increase in D.O., concur with TMDL findings and demonstrate effectiveness of nutrient load reduction in improving WQ Divergence in flow condition trends consistent with point source reduction exceeding nonpoint reductionDivergence in flow condition trends consistent with point source reduction exceeding nonpoint reduction Effect of recent meteorological conditions on the proportions of point and NPS load has moved FW worst-case WBID downstream, may be altering the composition of algae bloomsEffect of recent meteorological conditions on the proportions of point and NPS load has moved FW worst-case WBID downstream, may be altering the composition of algae blooms
