Total VGP inflows were then calculated to be the sum of the computed

streamflows for the upper and lower Fraser basins.

The computed VGP inflows represented the physical availability of water to
the project. However, a number of constraints limited the actual amount of
water which could be diverted:

1. The diversion in anyone month was limited to 600 cfs
(approximately 36,900 ac-ft).

2. The total diversion in anyone year was limited to 93,300 ac-ft.

3. The total of all diversion during any consecutive 10-year period
was limited to 683,000 ac-ft.

4. A minimum streamflow of 90 cfs, or the total inflow to the project,
whichever is less, must be maintained below the project in the
Colorado River.

5. Water rights senior in priority to the VGP were entitled to their
legal share of the computed inflows prior to any diversion by the
VGP.

6. The diversion in any month was limited to the available storage
capacity in Lake Granby. The CBT project was always given first
priority in utilizing Granby capacity.

7. Windy Gap may divert water only during the period from April to
July.

The model computed the WGP diversion according to the above limitations,
and then computed the total storage available to VGP demands. WGP storage
in Lake Granby was allowed to carry-over from one year to the next, but 10
percent of the WGP storage at the beginning of each April was allocated to
CBT as required in the Carriage Contract.

Demand for WGP water was computed as the sum of the demand by Loveland and
the demand by other allotters. The Loveland demand was set equal to the
demand remaining after full use of the Loveland Big Thompson River water
rights and CBT shares. The demand by other allotters was assumed to be
