(CSU) for their excess municipal return flows available on Fountain Creek. Because of conditions on the
river, CSU was unable to exchange their return flows into Pueblo Reservoir for storage and sold
approximately 2000 acre-feet to AGUA for $18 per acre-foot. AGUA also constructed two recharge
ponds through which they diverted replacement water during winter months when they had excess water
available. This allowed them to retain the replacement credit for AGUA's use and provide the credits in a
lagged manner every month of the year for several years.
Total Replacement Sources
At the time of submittal of the March 1, 2002 Plan, AGUA anticipated securing approximately 13,745
acre-feet of augmentation water for the 2002 plan year to meet approximately 13,625 acre-feet of stream
depletions. Credits carried over from the 2001 plan year and transit losses charged on Fountain Creek
were also calculated in the plan and accounts for the difference between the projected depletions and
projected replacement.
Of the 12,815 acre-feet of replacement water AGUA anticipated receiving from Pueblo, SECWCD and
Cherokee far the 2002 plan year, they received only 5,769 acre-feet. This caused AGUA to have to
amend their plan to reduce pumping allowed by their members and find alternative augmentation water
sources.
For comparison purposes: In the 2003 Plan AGUA projected 1,248 acre-feet of replacement credit from
2,689 shares of owned and leased Excelsior Ditch, 1,661 acre-feet from SECWCD, 1,102 acre-feet from
Cherokee, 78 acre-feet from Union Ditch shares and had approximately 225 acre-feet of Las Animas
Consolidated Article III water carried over from 2002. Replacement credits expected to be available to
AGUA for the 2003 plan year before losses totaled only 4,314 acre-feet. AGUA also offered an
augmentation scheme to its members owning ditch shares to provide those shares to AGUA for
augmentation of their well pumping. Excelsior Ditch irrigators, the Fremont School District (Union
Ditch, 78 acre-feet) and Catlin Canal irrigators participated.
