The Jefferson River

The Jefferson River is the largest of the three forks of the Missouri River with the mouth located near Twin Bridges. The structure of the Jefferson is a large riffle-pool with frequent armored banks. Despite summer dewatering for agricultural irrigation, the Jefferson will sometimes shine on cooler summer days.
