Show the size and location of one or another reservoir. As this report is written, it would appear that long strides toward amicable and satisfactory solution of these problems have been taken. All parties concerned are to be congratulated. All in all, notwithstanding delays that have occurred in the transmittal to the Congress of the Interior Department's report on the Colorado River Storage project and participating projects, the year covered by this report has been one of solid accomplishment that augurs well for the future and in which each member of the Commission, his staff and the people of his State can take pride. VI. HYDROLOGY Collection of stream flow records from the Water Resources Branch of the U. S. Geological Survey and from state offices has continued and all such records are readily available in the Commission's files. The Commission also receives, through the cooperation of the U. S. Weather Bureau, annual and monthly Climatological Data bulletins for Colorado, Utah, Wyoming, New Mexico and Arizona. This includes all five states of the Upper Colorado River Basin. The Commission also receives, through the cooperation of the U. S. Soil Conservation Service, reports on snow surveys made in cooperation with other agencies of federal and state governments. Those reports cover the states of Utah and Arizona, the drainage basin of the Colorado River, the Rio Grande and the Platte and Arkansas Rivers. These data, now in the Commission's files, make possible the detailed hydrologic investigations now underway in the engineering department. The table of gaging stations and stream discharges, which appeared in the First and Second Annual Reports, is again given as Appendix J in this Third Annual Report. Stream discharges for the water year 1951 have been added to the previous table in so far as the provisional records for these stations have been received. A few minor alterations and corrections have been made in the new table. No forecasts of water supply were made for the season of 1951, but a study is underway in the engineering department of methods and formulas for the forecasting of stream flow in the State of Colorado. A preliminary report on this study for forecasting the summer flow of the Roaring Fork at Glenwood Springs is given as Appendix F. This report indicates the methods adopted for the study .and formulas for this stream. Similar methods and formulas will be developed for the other principal streams of the State and -9- |
