<br />C\/ <br />- <br />.... <br />- <br />c: <br />C <br /> <br />No temperature or frost records during the 1946-1951 ,period <br /> <br />were required in the studies. <br /> <br />. <br /> <br />B. Historic stream Flow at Key Gaging Stations <br /> <br />Records of stream flow at key gaging stations for the period <br /> <br />1914-1945 are sho~m in Appendix A, Table 6 of the report. Those <br /> <br />records, to complete the study outlined in this Supplement Report, <br /> <br />were extended to cover the period 1946-1951. In some cases records <br /> <br />of new stations were utilized and in other cases a few of the <br /> <br />stations previously used were dropped where records have not been <br /> <br />maintained. <br /> <br />C. Drainage Areas Above Key Ga~ing Stations <br /> <br />The drainage areas upstream from gaging stations and other <br /> <br />division points were discussed and summarized in the report. In <br /> <br />the studies deriving estimates on the basis of drainage areas in <br /> <br />stream sections other than those listed in Table 2 of the report, <br /> <br />drainage area data as published in the Geological Survey water- <br /> <br />supply papers for the additional gaging stations were used. <br /> <br />D. Depletions of Ground-Water Basins <br />Further depletions of the ground-water basins in the Gila <br /> <br />River drainage area were determined for the 1946-1951 period for <br /> <br />the same four areas described in the report. The same methods <br /> <br />were employed in deriving the depletions for the 1946-1951 period <br /> <br />as were used in determining the 1914-1945 estimates. Table 14S 4 <br /> <br />summarizes the depletions of ground-water basins in the Gila fdver <br /> <br />drainage area during the 1946-1951 period. <br /> <br />3 <br />
