Lynden Levee Rehabilitation and Channel Realignment

Summary

This project included realigning a channel that runs adjacent to the Lynden Wastewater Treatment Plant and enhancing habitat in the newly created channel. It was constructed in conjunction with a levee improvement project by the US Army Corps of Engineers (USACE). The USACE project included replacing two existing culverts that penetrate the levee with a new culvert and fish-friendly flood gate, and restoring the levee crest and erosion protection. 

Project Update

Both projects were constructed in tandem between June to September 2021. Riparian planting at both project sites and mitigation sites will occur in winter 2022.
