This stud;' cOlJlbines the operation of the Viagon \Theel Gap Reserv-oir, with a total capacity of 500,000 acre-feet allocated as previously described for irr-ig8,tion, for neod control in Colorado am Newl!exico, am for cOLlpliance with the terlJS of tIle Rio Grame COIUp:lct. The major difference 'betrreen Studies 12 am 12-R is that in Study 12..R the content of Wagon Wheel Gap reservoir at the beginning of celemar year 1925 was zero, wlUJ.e in Study 12, tIle starting content was 241,000 acre-feet. The startinc content of zero was used in study 12-R to deter- mine the effects of bec;innine the reserv-oir operation during a dry cycle" such as has been e::perienced in the Rio Gran:le Basin during recent years. ( Run-off' at Wuon Wheel Gap Dam SJ;a, The monthly n-QV1S at Wagon Wheel Gap Dam site were estimated as flplrcentage of the news at the Wason gaging station, which lies within the reservoir area and five miles above the dam site.

These daily fl0\7s were used in computing the innow between Wagon Wheel Gap am Del Norte am for need control studies. To estimate the daily news at Wagon Wheel Gap, the Wagon Wheel Gap monthly now was divided by the Wason montbJ,y 1'low and this factor was applied to the Wason daiJ.y nOlJS for that month,," .- 'f' . , - L-___~ W9 ,...
