As the first step in considering this request, we have reviewed the <br />Corps of Engineers' 1978 flood hazard infol~ation report, and we are now in <br />agreement with the Corps that the predicted 100-year flood at the Dolores River <br />at Dolores gauge has a peak value of about 14,500 ft3/s. I have attached a <br />description of the analysis conducted to reach this agreement. The Cortez <br />Projects Office has compared the elevations of the levee portions now under <br />construction with the Corps 1978 report, and they feel there is adequate <br />freeboard to pass a flood peak of 14,500 fl:3/s. <br /> <br />- <br /> <br />. <br />.The next step is for you to contact Mr. McDonald to inform him of our agreement <br />with the Corps. Mr. McDonald will then be responsible for approac:hing local <br />interests to see if they are interested in ha,ving a continuous levee, if you <br />conclude that it is within the Bureau's aul:hority to con~truct such a levee. <br /> <br />Please let me know if I can be of furtl)er assistance. <br /> <br />NOTICE: IF YOU DETACH <br />ENCLOSllif.S PLWi lNSERJ <br />ClIIIE" I <br /> <br />. <br /> <br />~~ c/ aI~ <br /> <br />Attachment <br /> <br />bc: RegJ,onal Director, Salt Lake City, Utah <br />Attention: UC-700~j J' <br />'~ THIS Copy FOR <br /> <br />:/ <br />/- <br />
