t;"), ~-~-~) Table No. 7 shows results of the study. Column No. 2 of the Table indicates the recorded flow of the Rio Grande at Buckman. Column No. 3 represents the recorded flow at Alamosa. Column No. 4 represents what the flow at Buckman would have been had the river at Ala.mosa been dry. Column No. 5 indicates the estLmated drainage return to the stream assuming the Sump Drain to be constructed, and assuming a total of 100,000 acre feet to be returned to the stream from all sources above the mouth of the Sump Drain and above Alamosa. Column No. 6 represents the resulting flow at Buckman assuming the river to be dry at Alamosa, except for return flow. Column N9. 7 represents the esti1nated spill from the proposed reservoirs on the main Rio Grande in Colorado. Column No. 8 represents the estimated flow at Buckman under the proposed development in the San Luis Valley. Column No. 9 represents the estLmated flow at Buckman underconditions of 1927 taken from ColUll1Il No. ;5 of Table No. 46 of the Report on the Middle Rio Grande .t'roject. It may be noted by an inspection of the values in Columns Nos. 8 and 9 that in general the river at Buckman during the months of July, August and September would be improved by the proposed Colorado development on the main stem of the Rio Grande. This would improve the water supply for the Middle Rio Grande, as indicated in Table No.9, which shows the operation of the El Vado Reservoir as estimated in the Middle Rio Grande Report and the operation of the reservoir as it would be if the water supply at Bucbnan were as indicated in ColUll1Il No. 8 of Table No.7. Table No. 46 of the laddIe Rio Grande Report indicates that the Middle Rio Grande would have sustained C~. shortages in the years 1900, 1902 and 1904. The indicated shortages ~. - " .,., i.J..J -28_
