The Redwater watershed covers a total land area of 1,124 square miles in Montana and North Dakota. The area is a part of the Missouri River Basin and is characterized by its rolling hills and agricultural land use. The hydrology of the watershed is influenced by the Redwater River, which flows through the area and eventually empties into the Yellowstone River. The snowpack in the watershed is typically moderate, with an average snow water equivalent of around 6 inches. Surface water in the area is primarily used for irrigation and agricultural purposes, with several reservoirs present to help manage water resources. The watershed is also impacted by severe weather events such as drought, with a notable drought occurring in 2017. Climate trends in the area suggest increasing temperatures and more frequent extreme weather events.
