2017 Map of East Bay

About this map

Polson and the southern reaches of Flathead Lake anchor this 2017 survey, where the landscape transitions from the developed lakeshore to the steep elevations of Minesinger Ridge. The map details the intricate water management systems of the Mission Valley, including the Polson D Canal, Polson Z Canal, and the Bousquet Ditch, which redirect water across the valley floor. To the east, the terrain rises sharply toward the Hellroaring Reservoir and the drainage of Hell Roaring Creek. Small communities like Finley Point and Turtle Lake are shown with their contemporary road networks, such as S Shore Road and Finley Point Road, reflecting the area's mix of residential growth and agricultural heritage. Distinctive landmarks like Bird Point and Blumhagen Spring provide specific points of interest for those studying the local topography of Lake County.
