Moreau River
The Moreau River is a 200-mile-long tributary of the Missouri River that runs through Wyoming and South Dakota. It was named after Jean-Baptiste Moreau, an early French fur trader. The river's hydrology is dominated by snowmelt and summer rainfall, with peak flows occurring in May and June. The Moreau River is home to several dams, including the Shadehill Dam and Reservoir, which were built in the 1940s for flood control and water conservation purposes. The reservoir also serves as a popular recreational destination for fishing, boating, and camping. The river is also used for agricultural purposes, with irrigation canals diverting water to nearby farmland. The Moreau River has a rich history, with evidence of human habitation dating back over 10,000 years. Today, it remains an important resource for both people and wildlife in the region.
