The river is not controlled by any dams, but it does have a few tributaries such as the Little Minnesota River and the Mud Creek. The flow of the Whetstone River varies greatly throughout the year, with the highest levels typically occurring during the spring snowmelt and the lowest levels during the winter months. One interesting fact about the river is that it was once known for the abundance of freshwater mussels, but their populations have declined due to pollution and habitat destruction. College students interested in hydrology or environmental science may find the Whetstone River an interesting case study for studying streamflow dynamics and water quality issues.
