About this map

The Wells Dam powerhouse and spillway structure define the western edge of this 2017 survey, separating Lake Pateros from the northern reaches of Lake Entiat along the Columbia River. The map illustrates the complex intersection of the river's hydroelectric development with the high plateau of Douglas County. To the east, the landscape rises toward Dyer Hill and the small settlement of Dyer, which sits near the junction of Old Dyer and Central Ferry Canyon Rd.

Evidence of the region's agricultural and ranching layout is seen in the grid of rural roads and named landmarks like Bonita Flats and Sourdough Flats. Small water sources such as Ford Spring and Pattie Big Spring are vital points in this arid terrain. The map also records the presence of the small community of Howard and topographic features like Windsor Hill, providing a detailed look at the local geography between the river and the high basin of Boulder Park.
