About this map

The Salmo River meanders through this mountainous northern reach of Pend Oreille County, forming a complex drainage network near the international border. The landscape is defined by its hydrography, where the main river channel is fed by numerous tributaries including Swift Creek, Atkinson Creek, and Pete Creek. To the south, a small segment of the Pend-d'Oreille River is visible, joined by Russian Creek and Slate Creek.

Water bodies such as Rosebud Lake and Lomond Lake sit within the high-elevation terrain, reflecting the glacial and fluvial history of the Selkirk Mountains region. This 2023 survey emphasizes the natural riparian corridors and the network of drainages like Wallack Creek and McCormick Creek that carve through the timbered slopes, offering a precise look at the hydrology of the area north of the Boundary Dam reservoir.
