According to Utah - Wyoming agreement as shorm in joint memorandUm of October 16, 1947.
Determined by difference of, inflow - outflO1'; (Linwood) considering amount and location of channel losses.
Channel losses as shotffi in U,S.B.R, Region IV evaporation study.
According to Utah - Wyoming agreement. No channel losses assigned before junction with Green River.
According to Colorado - Wyoming agreement shorID in joint memorandum of April 7, 1947.
Estimated by Engineering Advisory Committee as 45 miles @ 150 A.F 0/ mile and 43 miles @ 300 A.F. ! mile.
,Estimated by Engineering Advisory Committee as 20 miles @ 600 A.F.! mile and 30 miles @ 200 A.Fo / mile.
Estimated by Engineering Advisory Committee as 80 miles @ 60 A.F./ mile.
Estimated by U.S.B.R. in Denver as 69 A.F. / sq. mile in Utah (based on average weighted precipitation)
drainage area in Utah - 340 sq. miles. Balance of flm.; at Gateway assigned to Colorado.
Estimated by U.S.B.R. in Denver as 300 A.F. / mile which is about 3/4 of per mile loss on Colorado River.
Estimated from average weighted precipitation.
As furnished by the State of Colorado (Final)
Total loss Cameo to Cisco (except Dolores) derived by difference in measured inflows (including Dolores
at Gate,,;ay minus losses to mouth) plus unmeasured flO1oJS minus the stream depletions (n) a.."ld the Cisco flm.,.
Losses in the section Cameo to Gisco considered to be a constant rate pet' r.ille and losses assigned based
. on the miles of channel in Colorado to the State Line thence prO::'rated according to volumes conveyed through
the section from the Colorado-Utah State Line to Cisco, Utah.
According to Colorado ~ New Mexico agreement at the Harch 24-26, 1948 meeting.
Estimated by. Colorado - Nev; Mexico
According to Colorado - Net.11exico agreement at the Ha.rch 24-26, 1948 meeting.
Estimated by the U.S.B.R. in Denver as miles @ A.F. / mile.
Derived by adding the estimated conveyance loss (t) to the measured flow at Lily, Colorado.
Pro-rated according to the volumes conveyed through the section.
Out of state channel loss.
l'lith in state channel loss.
