<br />00130J <br /> <br />. <br /> <br />. <br /> <br />Gunnison (county seat ot Gunnison County) northwest tor 15 miles up <br /> <br /> <br />Ohio Creak. By means ot a di tch, supplied by the Coal Creek outlet of <br /> <br /> <br />Lake Brennan, with headgate just below Irwin, releases trom Lake Brennan <br /> <br /> <br />could be carried to Ohio Pass at the head ot Ohio Creek. The only impor- <br /> <br /> <br />tant structure would be a siphon one-half mile long across the valley ot <br /> <br /> <br />Coal. Creek. <br /> <br /> <br />The advantage ot using Lake Brennan storage, ted to Ohio Creek <br /> <br /> <br />valley by way ot Ohio Pass, lies in the tact that Ohio Creek valley is <br /> <br /> <br />divided into an upper and a lower valley by a shallow gorge at a rail- <br /> <br /> <br />road siding called Hinkle 10 miles northwest of Gunnison. All return <br /> <br /> <br />flow trom irrigation in the upper valley is gathsred at this gorge and <br /> <br /> <br />brought back into the stream where it becomes available tor rediversion <br /> <br /> <br />in the lower valley. Return flow trom meadow hey lands being on the order <br /> <br /> <br />ot 70-80~, the stored water would be very etfective and would supply a <br /> <br /> <br />much larger area than is possible under other conditions or with other <br /> <br /> <br />Cil10ps. <br /> <br />. <br /> <br />There are, as yet, almost no records ot stream tlow or ot ir- <br /> <br /> <br />rigation use on Ohio Creak. When such records are obtained by the Bureau <br /> <br /> <br />ot Reclamation which is now collecting them, along with studies ot storage <br /> <br /> <br />possibilities on Castle Creek and Mill Creek, tributaries of Ohio Creek, <br /> <br /> <br />and at Hinkle on Ohio Creek itself, it may appear that the development ot <br /> <br /> <br />Lake Brennan storage tor use on Ohio Creek would ultimately be greatly <br /> <br /> <br />changed trom that now contemplated, but there is little doubt that water <br /> <br /> <br />must be brought to tho Ohio Creak area trom other sources, and Lake Bren- <br /> <br /> <br />nan seams the likeliest ot any. <br /> <br />-e- <br />
