Heavy rains are increasing runoff into the Missouri River Basin with flooding forecast on several tributaries downstream of Gavins Point Dam. Due to excessive rainfall, the U.S. Army Corps of Engineers will be reducing releases from Gavins Point Dam to 16,000 cfs.
The South Dakota Department of Public Safety (DPS), in collaboration with Governor Noem and the Department of Agriculture and Natural Resources’ (DANR) state geologist, is closely monitoring current and projected rainfall and river flows in southeast South Dakota using advanced computerized modeling.
DPS’ Office of Emergency Management has been in contact with Union County officials regarding Dakota Dunes and the potential impact of additional forecasted rainfall and runoff throughout the James, Vermillion, and Big Sioux River Basin that will increase the Missouri River flow levels. Peak flow levels in this area are expected between Monday and Tuesday (June 24-25, 2024).
The SD DPS is urging communities to stay vigilant by preparing for the potential of overland flooding, especially in low-lying areas and take necessary precautions to protect their homes, families, and properties.
Continue monitoring National Weather Service forecasts and messaging from your local officials.
