A habitat based assessment was conducted of the US Army Corps of Engineers' Lookout Point Dam and Reservoir Project on the Middle Fork Willamette River, Oregon, to determine losses or gains resulting from development and operation of the hydroelectric related components of the project. Preconstruction, postconstruction, and recent vegetation cover types of the project site were mapped based on aerial photographs from 1944, 1956, and 1979, respectively. Vegetation cover types were identified within the affected area and acreages of each type at each period were determined. Seventeen wildlife target species were selected to represent a cross-section of species groups affected by the project. An interagency team evaluated the suitability of the habitat to support the target species at each time period. An evaluation procedure which accounted for both the quantity and quality of habitat was used to aid in assessing impacts resulting from the project. The Lookout Point Project extensively altered or affected 6790 acres of land and river in the Middle Fork Willamette River drainage. Impacts to wildlife centered around the loss of 724 acres of old-growth conifer forest and 118 acres of riparian habitat. Impacts resulting from the Lookout Point Project included the loss of winter range for Roosevelt elk, and the loss of year-round habitat for black-tailed deer, western gray squirrel, red fox, mink, beaver, ruffed grouse, ring-necked pheasant, California quail, spotted owl, and other nongame species. Bald eagle and osprey were benefitted by an increase in foraging habitat. The potential of the affected area to support wildlife was greatly altered as a result of the Lookout Point Project. Loses or gains in the potential of the habitat to support wildlife will exist over the life of the project.
