The Bull Run Watershed Management Unit and Mt Hood National Forest dominate the landscape of this 1980s survey, highlighting the critical intersection of water resources and timberlands. The area is defined by the flow of the Sandy River and the Bull Run River, which feed essential infrastructure like the Bull Run Reservoir No. 2 and Roslyn Lake. These water bodies are supported by a network of industrial and utility features, including the Little Sandy Dam, Marmot Dam, and various gaging stations.
