Description Whatcom Creek has stream segments that do not meet Washington State water quality criteria for fecal coliform bacteria (FC). The Washington State Department of Ecology (Ecology) selected Whatcom Creek for a total maximum daily load (TMDL) study to address areas with water quality impairments.

In 2004, the City of Bellingham and Ecology published the Whatcom Creek TMDL report. Since then, the City of Bellingham’s Urban Streams Monitoring Program (USMP) has collected monthly water quality samples throughout Whatcom Creek and its tributaries.

This 2020 technical report provides a summary analysis of FC levels based on 2004-2018 USMP data. More recent FC data (2017–2018) were used to calculate FC percent reductions and establish target FC concentrations needed to meet water quality criteria.

Recommendations for updated loading capacities, load allocations, and wasteload allocations were developed using more recent FC data. These will be used to guide the updated TMDL and implementation plan for Whatcom Creek.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
