Maximum discharge along the river is currently at the Meramec River Near Eureka reporting a streamflow rate of 3,800 cfs. This is also the highest stage along the Meramec River, with a gauge stage of 5.49 ft at this location. This river is monitored from 5 different streamgauging stations along the Meramec River, the highest being situated at an altitude of 877 ft, the Meramec River At Cook Station.

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.

History of the River

The Meramec River (), sometimes spelled Maramec River is one of the longest free-flowing waterways in the U.S. state of Missouri, draining 3,980 square miles (10,300 km2) while wandering 218 miles (351 km) from headwaters near Salem to where it empties into the Mississippi River near St. Louis at Arnold and Oakville. The Meramec watershed covers
six Missouri Ozark Highland counties—Dent, Phelps, Crawford, Franklin, Jefferson, and St. Louis—and portions of eight others—Maries, Gasconade, Iron, Washington, Reynolds, St. Francois, Ste. Genevieve, and Texas. Between its source and its mouth, it falls 1,025 feet (312 m). Year-round navigability begins above Maramec Spring, just south of St. James. The Meramec's size increases at the confluence of the Dry Fork, and its navigability continues until the river enters the Mississippi at Arnold, Missouri.
