<br />tI The maximum discharge giyen tor Beaver Creek i~ that due to the storm which ocCurred more than 24 hours beCore th.e CaUure ol the Schaeffer reservoir (in the channel ot Bea. yer
<br />Creek, 9 miles above Us mouth). The amount passing the spillway and waste ga.tes oC the Schaeffer reservoir at the tIme DC the maximum natural dischar~e of Beaver Creek was
<br />computed to be 3,I00second~Ceet. To this was added the <irsi.nage to Bea.ver Crook {r-om6~..5 squa.re miles between the dam and the mouth. The maximum dIscharge ot Red Creek,
<br />thech1eftributary, was Jound to be4,490second~Ceet, or 93second-feet-persquaremile. Applying th1<; unit run-otI to the entire additional drainage area gives a run-on oC 6,370 second~
<br />Ceett which added tothe 3/100 second~leet passing the dam gives 8 total maximum natural discharge of 9,470 second~(eet (or Beaver Creek at its mouth. For the M'lximum
<br />discnarge due to the breaking oC the SChaeffer reservoir, see PP. 17-18.
<br />b The area ot 48 square miles is that of Turkey Creek below the Teller reservoir, as little or no water passed the (l:1m durin~ the period oCmaximum discharge of the cr~ek,
<br />c Tho discharge given above represents the computed di~lmrg~ at the mouth. The 1DeasnrlnR point was a considemble dIstance above the mouth, and the unit run.ot! llbon
<br />that point was applied to the area above the mouth to detennine the total diSCharge. The hYdraulic Cactors aro those for the point ot actual mCo'$t!rement.
<br />d 'Phe discharge of Arkansas River at Pueblo as given OU p. 20 was 10-3,000 second teet.
