Black Slough Reach Restoration Project
Main LIBC Line: (360)312-2000
LIBC Emergency Hotline: (360)380-6998

The Black Slough Reach Restoration Project (or Black Slough Project) is located on the South Fork (SF) Nooksack River near Van Zandt, river mile (RM) 1.5 and 3, and the Potter Road Bridge. Downstream portions of the Black Slough tributary channel may be included in the project design. The Black Slough Project aims to improve habitat conditions for endangered SF Nooksack early Chinook (chinook) salmon and reduce flood risk throughout the area.

First Community Workshop Scheduled for September 10th, 2024 at 6 pm!

Postcards will be mailed with more information.

Community Outreach

The Black Slough Reach Restoration Project, led by Lummi Nation and supported by its engineering team, Natural Systems Design + Coastal Geologic Services (NSD), and outreach consultant, Triangle (project team), is one of several similar projects currently underway in the area that you may already be aware of. The project is being planned in close coordination with these other efforts which include: ·

Current Work 

The project team is currently assessing geomorphic and hydraulic conditions in the river channel and adjacent banks and floodplains. Team members plan to conduct site visits within the next 3-4 weeks to gather the data necessary to complete these assessments. You may receive a phone call, email, or letter asking for permission to to access the river via your property.

Next Steps 

The engineering team will build upon existing understanding of geomorphic and hydrologic processes in the SFNR developed from recent project experience supporting the Nooksack Tribe with the Hardscrabble-Todd Reach and Homesteader Reach Restoration designs immediately upstream for the Black Slough project reach. The design team will collaborate with LNR to refine project objectives and identify project constraints.

A suite of conceptual design alternatives will be developed to include design elements such as removal of riprap bank hardening, riparian planting, targeted excavation to increase access to or establish new off-channel habitat, placement of ELJs, side channel creation, and suggestions for targeted land acquisition. At the conceptual design phase NSD will work to identify and advance the restoration potential of the reach, irrespective of FEMA floodplain and other permitting constraints. The alternatives will be presented to stakeholders during community workshops. Geomorphic, hydraulic, habitat, and climate change analyses will be completed to inform design development. The selected alternative will then be adapted to work within FEMA floodplain and other constraints to develop Preliminary and Final (90%) Design levels. Final (90%) Design plans, Basis of Design Report, materials schedules, and cost estimates will then be prepared. A Final Planset will then be prepared for construction.
