The downstream flow of the Trinity River was reduced to approximately 450 cubic feet per second, subsequently reducing high quality salmonid rearing and spawning habitat, which has drawn criticism from groups including the Yurok and Hoopa Valley tribes.
The model determined the design velocity and water surface elevations from the ELJ placement. Based on the analysis and modeling results, we prepared plans, specifications and cost estimates for construction of the ELJ.
Our work helped to address criticism of a dam on the California river that had reduced salmon habitat.
