RE: Report of Colorado Pumping and Offset Account Operations by Substitute Water Supply
Plans for the Period April 1,1999 to March 31, 2000

Dear Mr. Pope and Ms. Clay:

The pUrpose of this letter is to provide a report of the operations of six Substitute Water Supply
Plans (SWSP) approved by the Colorado State Engineer which have been required to deliver a
portion of their replacement water to the Offset Account created by the Resolution Concerning
an Offset Account in John Martin Reservoir for Colorado Pumping As Amended March
30, 1998 ("Resolution"), This requirement is based on the fact that the depletions caused by the
operations covered by these plans are estimated to produce depletions to usable Stateline flow
during some months of the year, This letter reports the monthly estimated depletions to usable
Stateline flow caused by the operations covered by each plan and accounts for the replacement of
these estimated depletions by making fully consumable water available to Kansas in the Offset
Account.

The table at Enclosure I shows the estimated depletions for each of the SWSPs which the
Colorado State Engineer has required be replaced using water delivered to the Offset Account.
The table at Enclosure 2 shows the flows recorded at Garden City, Kansas during the period of
this report. No replacements were required by the Colorado State Engineer during the periods
when there were substantial flows (> 100 cfs) past Garden City. Therefore, replacements were
required to be replaced by each of the SWSPs during parts of July, August, and September of
1999 and during part of January, 2000. The replacement requirements are summarized in the last
column of the table at Enclosure I. The table at Enclosure 3 shows the amount of water in the
