The U.S. Geological Survey StreamStats program can be used to estimate the magnitude of various annual exceedance probability floods such as the 50-year or 100-year floods at locations where no streamgage data are available. In eastern Colorado where few streamgages exist, the regional-flood equations used in StreamStats have large uncertainties.
In order to reduce these uncertainties, the U.S. Geological Survey, in cooperation with Colorado Department of Transportation, is operating a crest-stage gage network at 10 culverts in eastern Colorado. In addition to improving the regional-flood equations used by StreamStats, the data collected at these gages can be used to estimate the magnitude of various annual exceedance probability floods such as the 50-year or 100-year flood should these culverts need replacing.
Each crest-stage gage contains pressure transducers that record the water-surface elevation upstream and downstream from the culvert; the water-surface elevation is then used to determine the streamflow through the culvert. This study will provide 2 years of peak-streamflow data. The data will be stored in USGS National Water Information System.
