"The U.S. Army Corps of Engineers funds hatchery programs in the Willamette Basin to help mitigate impacts from the development and operation of the system of multi-purpose dams. Cramer Fish Sciences assembled a database of historic information on stocking of hatchery fish in the Willamette Basin. Using this database, they provided an assessment of impacts to ESA-listed salmonids resulting from stocking of catchable rainbow trout. We were very pleased with the thoroughness and quality of their work products and we hope to gain their assistance with future projects."
