The stream gauge measures the water level and flow rate of the river, which is influenced by precipitation, snowmelt, and groundwater inputs. The Minnesota River has several tributaries and dams along its course, including the Yellow Medicine River and the Lac qui Parle Dam. The river's flow rate is generally highest in the spring and lowest in the fall, due to seasonal precipitation patterns and agricultural water use. Interestingly, the Minnesota River is known for its high sediment load, which can cause flooding and water quality issues. Overall, understanding the hydrology of the Minnesota River is important for managing water resources in the region.
