<br /> <br />CCC879 <br /> <br />. <br /> <br />. <br /> <br />I <br /> <br />.. <br />. <br />. <br />I. <br />I <br /> <br />HISTORY <br /> <br />Interest in a water project in the Trinidad area <br />started in the early 1930's with concerns over severe <br /> <br />flooding in the purgatoire Valley. Several alternatives to <br /> <br />reduce or el iminate damage, including channel modif ication <br /> <br />and dams, were reviewed by the Corps of Engineers. Prelimi- <br />nary design of a dam at Sopris, about one mile upstream of <br /> <br />the present Trinidad Dam, was circulated for review in the <br /> <br />late 1930's. Subsequent economic studies revealed that a <br /> <br />single purpose dam, either flood or irrigation, was not <br />feasible. However, a multi-purpose dam and reservoir could <br /> <br />be justified. <br /> <br />The Corps of Engineers studied the flood control and <br />construction aspects of the project while the Bureau of <br />Reclamation (USBR) studied irrigation and water supply. The <br />USBR (1964) found that no decrease in available downstream <br />water would occur if inefficient lands (class 6W) in the <br /> <br />Trinidad area were removed from irrigation, an upper limit <br /> <br />of 19717 acres was irrigated (up to 40000 acres had been <br /> <br /> <br />irrigated historically) and Colorado water law was observed. <br /> <br />-2- <br /> <br />~!~~o/'~:'~ri"""_,,"y,,'r,. -<-~ .,_"_,,~,, . _, 'r <br />
