5 COLORADO GROUND-WATER REPORTS List compiled by Paul T. Voegeli, Sr.

PREFACE Since 1886 the U.S. Geological Survey has reported on the ground­ water resources of Colorado. The information reported ranges from brief descriptions to comprehensive geohydrologic interpretations. Information presented in the earlier reports is largely from Geological Survey papers devoted to economic geology. Many of the papers on economic geology contain ground-water data and interpretations. ~e early hydrologic publications deal chiefly with basic data. Before 1945, nearly all the reports were prepared exclusively by the Geological Survey. After 1945, most were prepared by the Geological Survey in cooperation with the Colorado Water Conservation Board.

Many reports, :lmclud:ing .. typewtitten, duplicated, and open-file reports, cited herein are available for reference at the office of the district geologist, Ground Water Branch, U.S. Geological Survey, Building 25, Denver Federal Center. Reports published by the Geological Survey as Professional Papers, Bulletins, and Water-Supply Papers may be consulted in larger public and university libraries. Geological Survey publications that are not out of print may be bought over the counter from the Geological Survey Public Inquiries Office, New Custom House, Denver, or by mail from the Superintendent of Documents, Washington, D.C.. Copies of Colorado Water Conservation Board Circulars or Basic-Data Reports that are not out of print may be obtained for a twenty-five-cent mailing charge from the Director, Colorado Water Conservation Board, State Services Building, Denver.

The reports cited herein are listed by area and county. (See figure l.)
