About this map

Wells Dam dominates this section of the Columbia River, serving as the dividing point between Lake Pateros and Lake Entiat. This 1968 field-checked record, revised in 1981, captures the industrial and agricultural landscape of the river valley, where the powerhouse and fish hatchery operate alongside the Burlington Northern railroad. The map preserves the location of the former settlement at Dyer (Site) on Dyer Hill, providing a clear view of the area's transition from riverfront operations to the high plateaus.

Away from the river, the terrain rises into the distinctive Cold Springs Basin and the broad expanse of Boulder Park. Numerous springs, such as Pottie Big Spring and Ford Spring, dot the landscape, highlighting the vital water sources for the upland Sourdough Flats. The presence of cisterns and a network of jeep trails suggests a landscape defined by livestock grazing and seasonal land use during the late twentieth century.
