About the ruby river

The Ruby River is a tributary of the Jefferson River, which eventually flows into the Missouri River. It is around 76 miles long and is located in southwestern Montana. The river was named after the garnets found in the area, which are a deep red color, like the precious stone. The river has a substantial flow and is used for irrigation of crops and pastures, as well as for recreational activities such as fishing, rafting, and kayaking. There are several reservoirs and dams along the river, including Ruby Reservoir, which was built in the 1930s to provide irrigation water for local farmers. The river has a rich history, as it was once home to Native American tribes and was an important site for fur trading in the 1800s.
