2011 Maple River Dam Flow Through

Water flowing through the Maple River Dam. The dam is a pass through dam that lets a limited amount of water (as shown in the video) flow through. During high streamflow conditions, water is stored (accumulates) in the reservoir. If the water rises high enough, it goes over a spillway to the left of this video.

The video was taken at approximately 12:30 pm CDT, Wednesday, April, 13, 2011. At that time the streamflow above the dam (inflow) was approximately 5,120 cubic feet per second (cfs).

The Maple River Dam is an earthen dam along the Maple River in southwest Cass County, N. Dak., and is owned and operated by the Cass County Joint Water Resource District. Construction was completed in 2006 to reduce the magnitude and duration of future flooding along the Maple, Sheyenne, Rush and Red Rivers in eastern North Dakota. The dam provides flood protection for downstream areas by temporarily impounding up to 60,000 acre-feet of water and reducing peak river stages along the Maple River, Sheyenne River, Rush River, and Red River in Cass County. Water runs over the concrete spillway at a stage of 48 feet or an elevation of approximately 1,048 feet.

Video was taken by U.S. Geological Survey while measuring streamflow. The public should not approach the dam.

The USGS has a streamflow gage representing inflow to the dam at ‪http://waterdata.usgs.gov/nd/nwis/uv/?site_no=05059715‬
