Water Quality AssessmentWater Quality Assessment
Low Flows In-stream water quality Pollutants of Concern WQBELs: water quality based effluent limits ADABCs: antidegradation based average
concentrations
![Page 8: The WQCD Permitting Perspective](https://reader035.fdocuments.in/reader035/viewer/2022062321/56813348550346895d9a44c2/html5/thumbnails/8.jpg)
Low FlowsLow Flows In-stream dilution
High low flows, small design flow = greater dilution
Low low flows, large design flow = lesser dilution
