Colorado DroughtWatchMore detailed information on drought in Colorado is available for: Map of below normal 7-day average streamflow compared to historical streamflow for the day of yearhttp://water.usgs.gov/waterwatch/images/state/co/pa07d_dry.gifThe "Below normal streamflow" map (from the USGS Drought Watch Web site) depicts 7-day average streamflow conditions as measured at USGS gaging stations. The colors represent 7-day average streamflow compared to percentiles of historical weekly streamflow for the week of the year. This map represents conditions adjusted for this time of the year. Only stations having at least 30 years of record are used. Uncolored circles depict stations having less than 30 years of record, having streamflows near or above normal, or that are currently not transmitting. The data used to produce this map are provisional and have not been reviewed or edited. They may be subject to significant change. |
