The Flathead River defines the complex hydrology of the Flathead Valley, carving a winding path through a landscape marked by numerous oxbows and quiet backwaters. This modern 2024 survey documents the dense network of waterways east of Evergreen, including McWenneger Slough, Shaws Slough, and the distinct curve of Half Moon Slough. These features reveal the historical movement of the river channel across the valley floor, creating fertile land that has long supported local agriculture.
