Upper Milk
Watershed Hydrology
The Upper Milk Watershed (HUC 10050002) spans approximately 5,666 square miles in the state of Montana. It is characterized by a complex hydrology system, including numerous small tributaries that feed into the Milk River. The watershed is also known for its high snowpack, with significant snow accumulation typically occurring from November through April. Surface water in the watershed is primarily used for agriculture, with irrigation being a dominant land use. Reservoirs within the watershed are used for both irrigation and municipal water supply. The climate in the Upper Milk Watershed is semi-arid, with hot summers and cold winters. The area experiences periodic droughts, which can impact water availability for agricultural and municipal use. Additionally, climate models suggest that the region may experience increased temperatures and decreased precipitation in the coming decades, which could further exacerbate water scarcity issues.
