account between December 14, 1997 and March 31, 1998 and all evaporation was charged to the
Flood Pool account during this time period.

During the period November I, 1997 through March 31, 1998 a total of215,040 a.f. was stored as
conservation storage.

Article I of the Operating Plan provides the following definitions:

A. "Periods of winter storage" consists ofthe period oftime commencing on November
I of each year and continuing to the first exhaustion of conservation storage during the
compact year.

B. "Summer storage season" shall be the period oftime commencing at the first
exhaustion of conservation storage and continuing to and including the next succeeding
October 31.

Furthermore, Article II of the Operating Plan provides that:

All inflows into John Martin Reservoir during a period of winter storage shall accrue to
conservation storage" and "all inflows entering said reservoir during a period of
conservation storage in the summer storage season shall accrue to conservation storage."

Since the first exhaustion of conservation storage during the 1997-98 compact year occurred at
0712 hr., September 5, 1998, technically the period of winter storage extended from November I,
1997 until September 5, 1998.

The accounting of the Operations Secretary has traditionally and continues herein to showall
inflows during the winter storage period as accruals to conservation storage, however, prior to
April I of each year such inflows are assigned to an account entitled "Winter Compact Water"
and afterward to an account entitled "Summer Compact Water." The latter account is also used
during periods of conservation storage in the summer storage season to show the accrual of
inflow to conservation storage. This accounting is done for the purpose of administering a certain
intrastate agreement among Colorado water nsers.

On and after April 1, 1998, while water remained in the Flood Pool account, conservation storage
continued to accrue at the rate of inflow pursuant to Article II B of the Operating Plan.

On April 7, 1998 releases of conservation storage into accounts began pursuant to Article II D of \'2)'\"\'6 Qt~l
