About this map

Hydrological management and protected mountain terrain define this 1989 study of the high country east of the Puget Sound lowlands. The landscape is dominated by the Cedar River Watershed (City of Seattle) and the Green River Watershed (City of Tacoma), highlighting the critical role these forests play in municipal water supply. Key water bodies such as Chester Morse Lake and the Howard A. Hanson Reservoir anchor the drainage systems, while smaller features like Eagle Lake and Tsuga Lakes dot the higher elevations.

Resource extraction and infrastructure are visible through numerous labels for Borrow Pits and Gravel Pits, along with a major Transmission Line traversing the southern portion of the sheet. The rugged topography is etched with drainage networks including Rex River, North Fork Green River, and Middle Fork Taylor Creek, all contained within the Snoqualmie National Forest. A notable Gaging Station on the Rex River indicates the active monitoring of these essential Pacific Northwest waterways.
