WESTERN COLORADO <br /> WATER LEVEL MEASUREMENTS <br /> 2021 <br /> This report updates basic data concerning the depth to and elevation of groundwater in three <br /> distinct regions of western Colorado. Most of the wells for which data are reported were <br /> originally constructed or identified in the 1970's by the United States Geological Survey (USGS) as <br /> a part of their statewide monitoring well network. The USGS monitoring effort was abandoned in <br /> 1982, and in 1991 the State of Colorado Division of Water Resources initiated a program to monitor <br /> water levels in about 55 wells of that former monitoring network. The number of monitored wells <br /> is sparse in some areas. <br /> The wells listed in this report are part of a statewide water-level monitoring network funded by <br /> Senate Bill 200 (1987 Legislative Session). That legislation directed that a portion of the fees <br /> collected for applications for water well permits be used for the establishment of a program to <br /> monitor groundwater levels throughout the state. <br /> Geographic areas covered in this report include: <br /> • San Juan basin - three wells <br /> o Fruitland and San Jose Formations <br /> • The Colorado Plateau and Grand Mesa - eleven wells <br /> o Mesa Verde Group, Dakota/Burro Canyon Formations <br /> • The Piceance basin - thirty-five wells <br /> o Green River, Parachute Creek, and Uinta Formations <br /> • Garfield and Mesa Counties - eight wells <br /> o Wasatch Formation <br /> The monitored wells are not evenly distributed in western Colorado, but are focused in specific <br /> basins or areas of interest. The well data are ordered alphabetically by well name. Maps for each <br /> of the four areas, displaying monitoring well locations and names, precede the data for individual <br /> wells. The specific aquifer being monitored in a well is listed on the data sheet for that well. <br /> All available water-level data for each well is plotted as a true time series. As in previous reports, <br /> the accompanying data table only lists data from the last 10 years. The report also contains data <br /> from wells, which are part of this monitoring effort, but for which measurements were not <br /> available in 2021. Wells lacking measurements in the past 10 years have been removed from the <br /> monitoring program and are no longer included in this publication. <br />
