Biological Assessment for Bureau of Reclamation Future Operations and Maintenance in the Tualatin River Subbasin

The Biological Assessment for Bureau of Reclamation Future Operations and Maintenance in the Tualatin River Subbasin, developed in compliance with the requirements of the Endangered Species Act, describes and evaluates the potential effects of the Tualatin Project operations on threatened and endangered species. Reclamation is in the process of evaluating the effects on endangered species for each of its project operations.

The biological assessment was sent to NOAA Fisheries and US Fish and Wildlife Service on April 20, 2009.

The Tualatin Project was authorized by Congress on September 20, 1966. The purpose of the Project is to supply irrigation water to agricultural lands in the Tualatin River Valley, Oregon, supply water for municipal and industrial use, enhance recreation opportunities, and provide for the conservation and development of fish and wildlife. Features include Scoggins Dam (Henry Hagg Lake), water distribution facilities, and irrigation canals and pipelines.
