1985 Map of Twin Lakes

About this map

North Twin Lake and South Twin Lake dominate the eastern edge of this landscape within the Colville Indian Reservation. This mid-1980s survey captures a high-elevation environment defined by steep drainages and prominent peaks like Lynx Mountain and Bitterroot Mtn. The hydrological network is well-defined, with Beaver Dam Creek, Granite Creek, and Lynx Creek carving through the terrain to feed the larger lake system. Near the lakeshore, the Rocky Point Campground indicates the area's use for recreation, while the Oregon City Ridge looms to the west. Localized industry is present in the form of a Borrow Pit near Boss Creek, while the surveyor also noted Johns Creek at the northern margin. The map provides a clear record of the road network and water bodies before further modern development, preserving the 1980s footprint of this part of Ferry County.
