Water resources of the Upper Colorado River Basin - basic data

This is the basic data section of a report by the U.S. Geological Survey on the water resources of the Upper Colorado River Basin. This section contains tables of duration of water discharge at 176 stream-gaging sites, monthly and annual summaries of chemical quality and sediment data at sites of continuous record, results of chemical quality and sediment analyses at miscellaneous-sampling sites, data on the chemical quality and other characteristics of ground water, and isohyetal maps of normal seasonal and annual precipitation. Also included is an inventory of surface-water records of streamflow, chemical quality, and suspended sediment. Location of gaging stations, chemical-quality and sediment-sampling sites, and wells and springs, are shown on a map of the Upper Colorado River Basin.
