Watershed Hydrology

The Two Medicine Watershed (HUC 10030201) is located in northwestern Montana and covers an area of approximately 850 square miles. The watershed is part of the Upper Missouri River Basin and is characterized by its high elevation and mountainous topography. The hydrology of the watershed is dominated by the Two Medicine River and its tributaries. These streams are fed by snowpack, which accumulates during the winter months and melts in the spring and summer. The snowpack is particularly important for water supply, as the area receives low amounts of precipitation throughout the year. Surface water in the watershed is generally of good quality, although some areas are affected by sediment and nutrient runoff from agricultural and urban sources. The region's reservoirs are used for both water supply and recreation, with fishing and boating being popular activities. Interesting climatic facts include the high elevation of the watershed, which results in cooler temperatures and more precipitation than surrounding areas. Trends in the region include decreasing snowpack and earlier snowmelt due to climate change, which could have impacts on water supply and ecology in the future.
