the 2002 pumping depletions would not accrue to the stream until following years (post plan depletions)
and the stream depletions resulting during the 2002 plan year would also include depletions accruing
from 1996 through 2001 plan year pumping. The total amount of projected depletions actually occurring
during the 2002 plan year were estimated to be 13,625 acre-feet for AGUA, MAGUA, Booth and the
SWSPs, as shown in Table 1 below.

AGUA's 2002 Plan provided augmentation water from four sources: 1) consumptive use credits from the
Excelsior Ditch; 2) transmountain and other reusable water from the Board of Water Works of Pueblo; 3)
transmountain return flow credits from the Southeastern Colorado Water Conservancy District; and 4)
reusable return flows from Cherokee Metropolitan District. A description of AGUA's interests in these
sources is discussed below. Contracts with Manitou Springs Sparklers, Inc. and Colorado City provide
augmentation credits to meet a small amount of depletions on tributaries. Additional replacement sources
that AGUA has been able to secure during the drought are also discussed below.
Excelsior Ditch
For the 2002 Plan, AGUA projected having control of a total of 1,677 shares out of 3,333 total
outstanding Excelsior Ditch shares (50.32 percent). AGUA owns 1,007 shares and planned to lease 440
shares from Mr. Dick Evans and 230 shares from Lafarge North America, Inc. Replacement credits from
AGUA's Excelsior Ditch shares are available to replace depletions that accrue to the Arkansas River
downstream of the Excelsior headgate and normally by exchange above the Excelsior headgate unless
there is a river call preventing it.
