River in St. Louis, Missouri

The River des Peres (French: rivière des Pères) (/lang//pron//d//ʌ/'/p//ɛər/) is a 9.3 mile (15 km) metropolitan river in St. Louis, Missouri. It is the backbone of sanitary and storm water systems in the city of St. Louis and portions of St. Louis County. Its largest tributaries are Deer Creek and Gravois Creek. At St. Louis, the river has a mean annual discharge of 79 cubic feet per second.

River des Peres enters underground culverts from north of Forest Park, emerges south of the park into concrete channels, and debouches into the Mississippi. An artificial water flow that emulates the river was created through Forest Park, using the city's water supply. This is often mistakenly considered a re creation of the original River des Peres. However, the water flow here is deliberately produced, not derived from rainfall, or runoff, etc., and cannot be considered a re creation of the river. The resemblance of the water feature to a picturesque river scene was an attempt to maintain continuity with the appearance of the rest of Forest Park's landscape, which for the most part, excepting significantly recent additions to the Art Museum (by Peter Walker), upholds the original, early twentieth century pastoral design intentions of George Kessler. The design received notable objections due to its generous use of resources to present the appearance of a healthy river. The river is currently part of the combined sewer and stormwater system of its watershed, which includes large portions of St. Louis City and County. It is administered by the St. Louis Metropolitan Sewer District (MSD), which concerns itself primarily with sanitary and storm water management; and the United States Army Corps of Engineers, which handles general flood and safety concerns. MSD is working to separate the sanitary and stormwater systems, which will enable more recreational use of the river. The planned River des Peres Greenway Project created an 11 mile (18 km) linear park along the river from Forest Park to the Mississippi. It is part of a larger system of works as part of the River Ring project by The Great Rivers Greenway District.
