Meeting water quality objectives from the Lake Whatcom TMDL is a component of the county’s permit. For more information visit the NPDES page.
The Lake Whatcom Comprehensive Stormwater Plan identifies a prioritized list of new stormwater treatment capital projects in the Lake Whatcom watershed. This list is used to identify projects for the six-year plan (the Water Resources Improvement Program or "WRIP"). In 2017, Whatcom County Public Works completed the process of updating the stormwater capital program component of the Lake Whatcom Comprehensive Stormwater Plan.
