About this file

This document is a comprehensive geospatial map illustrating the Lower Granite Natural Resource Management (NRM) Project Area, produced by the U.S. Army Corps of Engineers Walla Walla District in May 2023. The map covers a significant geographical region spanning multiple counties in Washington State, including Franklin, Whitman, Columbia, Garfield, Asotin, Nez Perce, and Latah Counties, and details the area around the Lower Granite Dam, Little Goose Dam, and Lower Monumental Dam.

The map precisely identifies numerous Habitat Management Units (HMUs), recreation areas, outgrants, landings, parks, and key infrastructure such as pump plants, trails, and boat ramps. Key locations include Lyons Ferry State Park, Hells Gate State Park, Chief Timothy Park, and various landings like Wawawai, Illia, and Nisqually John. The map also highlights geographical features, county boundaries, and provides a detailed inset of the Lewiston-Clarkston area, with a disclaimer about the potential variability in geospatial data accuracy. The document serves as a comprehensive geographical reference for the Lower Granite Natural Resource Management Project Area.
