Twin Lakes/Mt. Elbert forebay combined storage totaled 84,190 acre-feet
at the end of the water year. Twin Lakes storage was 74,750 acre-feet
and Mt. Elbert Forebay was 9,440 acre-feet.:

At the end of water year 1988, Pueblo Reservoir content was
150,780 acre-feet. The Winter Water Storage Program was in effect from
November 15 through March 14 allowing the maximum daily storage in
Pueblo Reservoir of 40,990 acre-feet of water. Of the 40,990 acre-feet of
winter water stored, 33,340 acre-feet was released, 1,300 acre-feet
evaporated and 6,350 acre-feet remainedi:n storage at the end of the
water year. In addition to the 1988-1989 winter water releases,
3,820 acre-feet of 1987-1988 winter water ~as released and 76 acre-feet
evaporated, also 91,710 acre-feet of West Slppe imports were released with
an addition 8,350 acre-feet lost to evaporation. Pueblo Reservoir
reached its maximum storage on May 4 with an elevation of 4864.06 feet
and content of 167,650 acre-feet.

The below average native runoff in the Arkansas River and the below
normal precipitation in the basin (exhibi~s 14 and 15) required heavy
storage demands. Winter water began releases in late March and
cont i nued through mi d-May then agai n from mi d-June through September.
Project water demands began in 1 ate June: and continued through early
September.

The water year ended wi th 113,430 acre-feet of water in storage in
Pueblo Reservoir. The 1988-1989 winter water storage is shown on
exhibit 16 and the releases are shown on exhibit 17.

The pan evaporation rate used for computinq Pueblo Reservoir evaporation
is shown on exhibit 18. Table 8 and exh,bit 19 show Pueblo Reservoir
operations during water year 1989. :
