| Abstract | Long Description |
As part of the Lower Skagit Total Maximum Daily Load (TMDL) Study, a series of surveys were conducted in 1994 and 1995. This report presents the data collected during those surveys, as well as a summary of the Quality Assurance and Quality Control analysis of the data. The full report on the Lower Skagit TMDL will be published separately. Preliminary analysis showed widespread elevated levels of FC bacteria and turbidity in tributary streams, stormwater, drainage pump stations, combined sewer overflows, and point sources. In the Skagit River, turbidity and bacteria problems appear to be largely transported from the upper basin to the lower river. Dissolved Oxygen (DO) met the Water Quality Standards throughout the lower Skagit River, but the South Fork Skagit River showed evidence of being the critical location for low DO levels. |
