About the jefferson river


The Jefferson River is a tributary of the Missouri River, located in the western United States. It is approximately 83 miles long and runs through Montana. The river was named after Thomas Jefferson, who sent Meriwether Lewis and William Clark on an expedition to explore the river and its surroundings. The Jefferson River originates in the mountains of southwestern Montana and flows north through the Jefferson Valley. The river is primarily used for irrigation and agriculture, but there are also several recreational activities available, such as fishing, kayaking, and rafting. There are several dams and reservoirs along the Jefferson River, including the Canyon Ferry Dam and Reservoir and the Blacktail Dam, which provide hydroelectric power and irrigation water. Overall, the Jefferson River is an important natural resource for Montana's economy and environment.
