ADDITIONAL INFORMATION

This streamflow gaging station currently is operated by the Colorado Division of 
Water Resources (DWR). The USGS works cooperatively with the DWR to publish 
daily mean (and annual peak) discharge data for this station.
These are the only streamflow data available in NWISWeb for this site.
Current streamflow data (and other historical streamflow data) for this site 
are available on the DWR Colorado's Surface Water Conditions pages.
