Completed Lower Nooksack River Plans & Studies

The lower Nooksack River starts at the confluence of the three upper forks near Deming and flows downstream to Bellingham Bay. The lower river experiences the most severe damages during flood events and has been the focus for several comprehensive planning efforts. Completed plans are listed and available for download below. Some large files take extra time to load.

Nooksack River System-Wide Improvement Framework (SWIF)

This recently completed plan provides a systematic approach for resolving deficiencies identified during recent levee inspections so that the levees remain eligible for repair through the U.S. Army Corps of Engineers (ACOE) PL 84-99 Rehabilitation Program.

Lower Nooksack River Comprehensive Flood Hazard Management Plan (CFHMP)

Adopted in 1999, this plan provides detailed recommendations for flood hazard reduction strategies along the lower Nooksack River. The plan is currently being updated to integrate flood management strategies with the needs of salmon and the agricultural land uses within the floodplain.
During and since development of the CFHMP, several studies have been completed to advance specific project components recommended in the plan.

Hydrologic & Hydraulic Analyses

Sediment Management Studies

Geomorphic Investigations

Reach-Specific Integrated Project Planning

Reach 1: Interstate 5 to Bellingham Bay
Reach 4: Confluence of Upper Forks near Deming to Everson Bridge

Salmon and Salmon Habitat

In addition to flood planning, local resource agencies developed a Salmonid Recovery Plan for the Noosack River watershed and coastal tributaries within Whatcom County (Water Resource Inventory Area Number 1 or WRIA1). The plan, habitat assessments, and other salmon-related studies can be found on the WRIA 1 Salmon Recovery Board website
