<br />1 ~36 <br /> <br />During F. Y. 1957, field work and <br />compilation of data will continue with two <br />geologists working full time'.and one <br />engineer, one geologist, and one surveying <br />crew working part time. It is <br />anticipated that the inventory of wells <br />will be 100 percent completed, that the <br />geologic mapping will be about 30 percent <br />completed, that the determination of <br />altitudes of wells and test holes will be <br />30 percent completed, and that the pumping <br />and flow .tests will be about 40 percent <br />completed during the present fi~ld season. <br /> <br />3. Yuma County - Work on the Yuma <br />County project will begin in July with one geologist <br />on duty full time and ore geologist and one <br />engineer on duty part time. This study will <br />be a detailed study similar to the study <br />of Kit Carson County and will require about <br />3 years to complete. Maps to be prepared <br />for this project include depth-to-bedrock, <br />bedrock contour, depth-to-water, watertable <br />contour, and saturated thickness. A report, <br />similar in size and content to the Baca County <br />report, will be prepared. It is anticipated <br />that the field work in Yuma County will be <br />about 30 percent completed in F. Y. 1957. <br /> <br />I <br /> <br />4. Denver Metropolitan Area - The oldest <br />and one of the most serious ground-water <br />problems in Colorado is the problem of <br />declining water levels in the Denver Metropolitan <br />area--principally in the deep artesian wells. <br />Although not generally known, ground water has <br />been used extensively for munici~,l, industrial, <br />and other purposes in Denver and vicinity for more <br />than 75 years. As early as 1887 there were more <br />than 200 flowing wells in downtown Denver. <br />Many of those wells are still in use although <br />the pressure head has declined nearly 700 feet <br />in the downtown area. <br /> <br />With the rapid post-war expansion of <br />population in the Denver Metropolitan area and <br />with modern improvements in well-drilling and <br />pumping equipment, there has been a tremendous <br />expansion in the drilling business during which <br />thousands of wells have been drilled in Denver <br />and vicinity for use by municipalities (inclUding <br />Denver), housing developments, industries, and <br />by private individuals for domestic use or for <br />lawn irrigation. The problem has become so <br />serious that Federal home-loan agencies such as <br />the Federal Housing Administration and the <br />Veterans Administration have ceased making loans <br /> <br />I <br />
