The Apple Plum Watershed (HUC 07060005) spans across parts of Idaho and Montana, covering approximately 2,500 square miles. The watershed is primarily composed of mountainous terrain, with elevations ranging from 3,000 to 9,000 feet above sea level. The area experiences a semi-arid climate, with precipitation mostly occurring in the form of snow during the winter months. The watershed is fed by several tributaries, with the Clark Fork River serving as the main channel. The region is known for its significant snowpack, which provides a critical water source for the watershed during the dry summer months. The watershed also contains several large reservoirs, including the Thompson Falls Reservoir and Noxon Rapids Reservoir. In recent years, the region has experienced warming temperatures and decreased snowpack, leading to concerns about water availability for the local communities and ecosystems. Additionally, the area has seen an increase in extreme weather events, including drought and wildfires. These trends highlight the importance of effective water management and conservation efforts in the Apple Plum Watershed.
