EAGLE BUTTE, S.D. — The Cheyenne River which is the southern border of the Cheyenne River Agency has reached flood stages in the past few days. It is expected to continue to experiencing minor flooding as ice jams work loose and warmer weather melts record snowfall in the watershed.

The Moreau River valley is in the beginning stages of flooding and the Cheyenne River Sioux Tribe is expecting major flooding along the entirety of the Moreau River within reservation boundaries. BIA route 2 and BIA route 7 have flooding across the roads and are being worked on to keep open.

Crews have been working reservation wide clearing culverts and diverting drainage ditches to flow more efficiently. This is being done to decrease the immediate impact of flooding in low lying areas. The Cheyenne River Sioux Tribe has begun stockpiling water removal equipment, sandbags, boats and emergency supplies in anticipation of major flooding in the Moreau River valley.

The Cheyenne River Sioux Tribe has been working with outside agencies daily to understand the effect of the weather, flow of water through dams and monitoring systems on both rivers to gather data. Continual visual inspection of rivers are being conducted to ensure the most accurate information is available to dedicate resources.

“We need to continue to work together and I commend all of our employees that have been working to ensure that our people can live and travel safely,” said Chairman Harold Frazier.
