<br />o <br />~ <br /><.0 <br />.... <br /> <br />. <br /> <br />. <br /> <br />assumed that all of the stock ponds in the watershed of the <br /> <br />Purgatoire River upstream from the Trinidad gage would be filled <br /> <br />in the first major storm (more than l.25 inches of precipitation) <br /> <br />occurring during the months of May and June. This assumption, of <br /> <br />course, would presume that a major storm occurring during either <br /> <br />of these months was of watershed-wide significance. An examina- <br /> <br />tion of the stream flow records did not indicate that this was <br /> <br />always the case. As a matter of fact it appeared that this was <br /> <br />probably the case in approximately 50 percent of the years. <br /> <br />From the stream flow records it appears that in seven <br /> <br />years of the sixteen studied, the storms recorded by the Trinidad <br /> <br />weather station were probably watershed-wide. The total capacity <br /> <br />of the stock ponds located upstream from the Trinidad gaging <br /> <br />station, in the purgatoire River Basin, is 518 acre-feet. If we <br /> <br />are to assume that all of the stock ponds were filled during the <br /> <br />first major spring storm which is probably watershed-wide, the <br /> <br />theoretical effect upon the flood flows passing the Trinidad gage <br /> <br />would be in the magnitude of l.69 percent. This is undoubtedly <br /> <br />the highest possible percentage effect the stock ponds could have <br /> <br />upon the flows at the Trinidad gage. This percentage does not <br /> <br />take into account the channel losses that would occur if this <br /> <br />water were not, impounded by the stock ponds. The channel charac- <br /> <br />teristics downstream from the stock ponds are generally broad with <br /> <br />-4- <br />
