• Peak storm runoff estimates were made for various locations on <br />Davis and Middle Fork creeks. Both general storms and thunder- <br />storms were analyzed. Three different flood estimates were used. <br />These assumptions (as per Bureau of Reclamation) relate to the <br />degree of damage that would be realized in the event of failure <br />of a hydraulic control structure. The estimates, prepared by <br />using the SCS unitgraph method, are as follows: <br />Peak flow, cfs <br /> Davis Creek Middle Fork <br />Type of Storm D-2a D-7b Creek, B-3o <br /> <br />Thunderstorm (1 hr) <br />t <br />PMF <br />7,600 <br />9,700 <br />10,800 <br />Assumption A 4,900 6,200 6,900 <br />• Assumption B 1,700 3,160 2,400 <br />General Storm (18 hr) <br />PMF 750 1,240 1,320 <br />Assumption A 500 780 840 <br />Assumption B 190 280 320 <br />a.
