Many points on the Sheyenne River reached all-time record streamflows during the past week, according to real-time U.S. Geological Survey streamgage data.
During the last few days, steamflow at most USGS gaging stations in the Sheyenne River Basin upstream of Lake Ashtabula reached their highest levels since streamgaging began about 65 years ago. A new maximum streamflow of 7,560 cubic feet per second was set at the Sheyenne River near Warwick, N.D. on April 11, breaking the previous peak of 4,930 cubic feet per second set during the 2009 flood. Also, a new maximum streamflow of 7,000 cubic feet per second was set at the Sheyenne River below Baldhill Dam on April 13.
“Since early April, six USGS hydrographers have been servicing the 25 streamgages in the Sheyenne River Basin and measuring streamflow and water levels at all stations,” said Gregg Wiche, director of the USGS North Dakota Water Science Center. “The USGS data are used by various National, State, and local agencies for flood forecasts, the operation of dams, the design of levees, and decision making.”
The USGS collects data from more than 100 streamgages in North Dakota, most of which provide real-time data that is transmitted every hour. For the latest and most accurate streamflow data for North Dakota, visit the real-time streamflow web page.
Links to graphics that allow for comparison of the current river stage to historical peaks and to the National Weather Service flood stage are available on the USGS WaterWatch web page for North Dakota or through links on the USGS North Dakota Water Science Center flood web page.
For more than 125 years, the USGS has monitored flow in selected streams and rivers across the U.S. The information is routinely used for water supply and management, monitoring floods and droughts, bridge and road design, determination of flood risk, and for many recreational activities.
Note to media representatives: USGS crews will be measuring streamflow in the Valley City area for the next several days. News media interested in accompanying a USGS crew may contact Marisa Lubeck at 303-202-4765 or firstname.lastname@example.org.
