HDR hired Waterways as a subconsultant to evaluate geomorphic and sediment conditions and support HDR in development of potential project alternatives. Waterways completed their scope of work in 2010 and submitted a geomorphic report. Since then, the project partners have decided to expand the scope of work beyond Dairy Creek and evaluate the Sturgeon Lake system. Waterways’ role in an expanded scope of work would include revising the geomorphic report to evaluate historic, current and future trends for the entire Sturgeon Lake system, assemble and digitize the sediment budget analysis that was previously prepared by Dr. Peter Klingeman at Oregon State University, and update the sediment budget using recent data collected by the Corps and WMSWCD and recent hydraulic modeling. Waterways is also supporting HDR in development of a set of restoration actions to restore fish access and improve habitat quality in Sturgeon Lake.
