About this file
This document is a technical plan view drawing for the Little Goose Dam Stilling Basin Sediment Removal project located on the Snake River, spanning Oregon, Washington, and Idaho. The plan, issued by the U.S. Army Corps of Engineers Walla Walla District in July 2025, details the overall site layout for the Little Goose Dam, including key infrastructure elements such as the powerhouse, spillway, navigation lock, and fishway channel. The drawing provides specific details about boat restricted zones, a fish facility barge dock, Texas Rapids boat launch, and surrounding site features, with precise geographic coordinates and elevation data. Notable annotations include provisions for mooring floating plants at the fish facility dock, bird deterrent wire locations, and maintenance of public access to the Texas Rapids Park during construction.
