Water-resources data for Colorado for the 2001 water year consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; meteorological data; and water levels and water quality of wells and springs. This report (Volumes 1 and 2) contains discharge records for 313 gaging stations, stage and contents of 16 lakes and reservoirs, discharge measurements for 1 partial-record low-flow station and 1 miscellaneous site, peak-flow information for 22 crest-stage partial-record stations; water quality for 125 gaging stations and for 10 lakes and reservoirs, supplemental water quality for 181 gaged sites; water quality for 77 miscellaneous sites and 14 observation wells; water levels for 3 observation wells, and meteorological data for 55 sites. Three pertinent stations operated by bordering States also are included in this report. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey under the direction of W.F. Horak, District Chief. These data represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies.
