811.(2 . ~oc) 001'11 Report of U.S. Geological Survey Water-Resources Activities in the Arkansas River Basin of Colorado to the Arkansas River Compact Administration December 7, 1999 Items of Direct Interest to the Administration The USGS again received small decreases in funding for the Federal Collection of Basic Records Program in 1999, and additional cuts are expected through 2000 as part of the agreement to balance the Federal budget. This program provides basic station funding for 6 of the stations operated in support of the CQmpact (4 in Colorado and 2 in Kansas). Although funding for Compact stations was not affected in 1999, continued decreases in funding could affect these stations in the future. During 1999, the USGS in cooperation with the Colorado State Engineer completed a study to compare the power conversion coefficient (PCC) method to totalizing flow meters (TFM) for estimating ground-water pumpage in the lower Arkansas River valley alluvial aquifer of Colorado. The report is WRIR 99-4221 'Comparison of two approaches for determining ground- water discharge and pump age in the lower Arkansas River basin, Colorado, 1997-98.' Items of General Interest During 1999, the USGS will operate continuous-recording stream gages at about 55 sites in the basm, continuous-recording gages at 3 reservoirs, continuous recording water-quality stations at 13 sites. The USGS will conduct sediment data collection at about 15 sites, periodic water-quality measurements on Pueblo Reservoir, biological sampling at about 5 sites, and periodic water- quality sampling at about 35 surface-water sites and 165 wells (including about 150 wells at the U.S. Army's Pueblo Chemical Depot and 15 wells near Colorado Springs). Several networks of ground-water level measurements are operated in the basin, including 70 wells measured twice a year between Pueblo and the state line, 40 wells measured twice a year between Leadville and Pueblo, 40 wells measured twice a year in the alluvial aquifer south of Colorado Springs, 30 wells measured every other month in the Upper Black Squirrel Creek 13~in and 130 wells measured annually in EI Paso County. Much of the continuous-recording streamflow and water-quality data are available on the World Wide Web at http://co.water.usgs.gov/ The cooperative program between the USGS, U.S. Army, Agriculture Research SerVice, and Natural Resource Conservation Service of monitoring precipitation, streamflow, water quality, and suspended sediment at the U.S. Army's Pinon Canyon Maneuver Site along the Purgatoire
