| Short Description |
Water quality of tributaries in the Snohomish River drainage are assessed using data collected by Ecology and Snohomish County. Overall, water quality in Quilceda Creek, Allen Creek, French Creek, Woods Creek, the Marshland, and parts of the Pilchuck River violate water quality standards for fecal coliform. The violations are more extensive during the dry season (May-October). In addition, violations of the dissolved oxygen criterion occur during the dry season in Quilceda Creek, Allen Creek, French Creek, and the Marshland. (Also see abstract below) | |

| Abstract | Long Description |
Water quality of tributaries in the Snohomish River drainage are assessed using data collected by Ecology and Snohomish County. Overall, water quality in Quilceda Creek, Allen Creek, French Creek, Woods Creek, the Marshland, and parts of the Pilchuck River violate water quality standards for fecal coliform. The violations are more extensive during the dry season (May-October). In addition, violations of the dissolved oxygen criterion occur during the dry season in Quilceda Creek, Allen Creek, French Creek, and the Marshland. Water quality in all of the study basins is being adversely impacted by nonpoint sources of pollution. Total Maximum Daily Loads (TMDLs) and load allocations (LAs) are recommended for fecal coliform, but are also expected to mitigate other water quality issues in the study area. Watershed management plans should be implemented under WAC 400-12 (the "nonpoint rule") to achieve necessary reductions and thus meet water quality standards. |
