<br />'.' _.~ <br /> <br />. <br /> <br />. <br /> <br />REPORT OF THE WATER RESOURCES DIVISION <br /> <br />U. S. Geological Survey <br /> <br />February 28, 1967 <br /> <br />Thad McLaughlin has been designated the Regional Hydrologist for <br />the Rocky Mountain Region replacing S. Keith Jackson who retired last <br />December. <br /> <br />The Colorado Ground Water, Surface Water, and Quality of Water Branch <br />District offices have been reorganized into a Water Resources Division <br />District. The reorganization was effected to provide more efficient <br />operation of the overall water resources investigations in the State. <br />E. A. Moulder is the District Chief and J. W. Odel1 is the Assistant <br />District Chief. <br /> <br />The water supply outlook for Colorado for the year varies from <br />near normal to below normal. Precipitation at low elevation weather <br />stations was much below normal during February. Although there are <br />reports of substantial snowfal1 in some of the mountain areas, an <br />evaluation of conditions will not be made until the results of the <br />March 1 snow surveys are available. <br /> <br />A mass measurement of about 400 wells in Baca and southern <br />Prowers Counties was made during the week of January 23 to provide <br />data for water level change maps. Wells in the adjacent parts of <br />Kansas and Oklahoma were measured during the same period. <br /> <br />Several smaIl diameter observation wells were installed in the <br />South Platte Val1ey east of Greeley during the week of February 20, <br />to collect water level data near the river in areas where there are <br />no wells. <br /> <br />The relatively mild winter permitted limited field work to con- <br />tinue on the Rio Grande basin project. Measurements of discharge and <br />specific conductance of 14 ungaged streams in the Rio Grande basin <br />were made during February. Pumping tests were conducted on several <br />wells in the basin. Office computations and compilation of hydrologic <br />data were carried on concurrently with the limited field investigation. <br /> <br />The report, "Water Resources Data for Colorado - Part 2, Quality <br />of Water Records, 1965," has been transmitted to the printer. It <br />should be available for distribution by the middle of April. <br /> <br />1 <br /> <br />119c\ <br />
