About the meramec river

The Meramec River is a 218-mile-long tributary of the Mississippi River that flows through eastern Missouri. The river has played a significant role in the history of the region, serving as a transportation route for Native Americans and early settlers. The river has also been the site of several notable floods, including the devastating floods of 1993 and 2015. The river's hydrology is influenced by numerous tributaries, including the Bourbeuse and Big Rivers. The Meramec River is home to several reservoirs and dams, including the Meramec State Park Dam and the Fenton City Park Dam. These structures serve a variety of purposes, including flood control and hydroelectric power generation. The river is popular for recreational activities, including fishing, canoeing, and camping, and also supports a thriving agricultural industry.
