Sanderson Heights

The same procedure as used for S~lp"hur Creek was applied to determine peak

runoff flows from Sanderson Heights at Fifth Street in Meeker except that 1) the

unit hydrograph was derived from the same S-curve used by the Sacramento District

Corps of Engineers to determine runofffrom local washes in Rangely, Colorado, and

2) one hour point rainfall 'values for Meeker were not reduced because of the small

basin size. Data used in the computations are shown in Table 2 and the resultant
