Bismarck, N.D. (AP) The U.S. Geological Survey says above-normal precipitation last month led to record-breaking flows at several stream gauges in the southwest North Dakota. Agency spokesman Steve Robinson says the unusually wet august was most evident at gauges on the Heart, Knife and Green rivers. There are 140 USGS-operated stations in North Dakota that measure water levels, stream flow, rainfall and water-quality. Most of the USGS stations are real-time sites where data are updated every one to four hours. The USGS says it shares its data with the National Weather Service for flood forecasts and the U.S. Army Corps of Engineers for Flood Control Management. State and local agencies also use the data for flood response efforts.
