Use Scen~rio. In the Moderate Future Level Use Scenario( the water
use in the basin was increased above thf;l Existing Level by an
aimualaverage of 17,000 af of in-.basin M.& I depletions and 21,000
af of tra,nsmountain diversions.

In the High Future Level U.s<;! Scenario, the averflge annu,al water use
was increased to provide an additional 61,000 af for in-.basin
irrigation, municipal and industrial useS- oth<;!r. than oil shal<;!;
133;000 at: for oil shale development; . and 36,000 af, for
transmQuntain div.ersions.

Programs, Of this total, 3 I 000 af was supplied from the Green
Mountain Reservoir Water Marketing Sales in all three scenarios;
and 3,000 af and 40,000 af were provided under the Ruedi Reservoir
Water Marketing Sales in the Moderate and High Future Level Use
Scenarios, respectively. The balance of the. 93,000 afannual
demand for. oil shale in the High Future Level USe Scenario was
assumed to 'be. sUpplied from the Colo,rado River in the vicinity of
Parachute ahd DeBeque and in the Main Elk creek Basin.

A comparison of the total water demands
