The Nisqually Tribe has completed multiple phases of restoration over appoximately 15 years around Red Salmon Slough, an approximately 331 acre portion of the Nisqually Delta north of I-5, and east of the Nisqually River. This effort compliments the Nisqually Refuge Restoration resulting in the largest river delta restoration in the history of Puget Sound (as of 2012).
Pilot
MITIGATION 1996: The earliest work involved a small dike breach on the northern edge of the site for mitigation. Restored 9 acres.
Phase 1
EARLY SITE 2002: The next phase involved more extensive dike removal along the NW corner of the site. Restored 31 acres.
Phase 2
BRAGGETT FARM 2006: The next phase involved restoration of tidal flow to the old Braggett farm along the Southern portion of the site. Restored 100 acres.
Revegetation
2009: Another phase involved planting approximately 45 acres of surge plain woody vegetation. ESRP deliverables documents the planting process.
Phase 3
LEVEE REMOVAL 2011: The final phase involved removal of remnant dikes and levees throughout the site.
Notes
- Unlike the Nisqually Refuge Restoration no one archive provides technical information about the restoration of the site.
- Florian Leischner was project manager for the Nisqually Tribe.
- Wiltermood and Associates provided design and monitoring for most phases of the project, and may have the most complete technical record.
- Chris Ellings with the Nisqually Tribe led fish sampling.
- The final phases of the project were funded by NOAA Restoration Center the Estuary and Salmon Restoration Program.
