, Full seNice irrigation water for the Southem Ute Indian and Ute Mountain Ute Tribes deferred to Phase n
will be available in Phase I at Ridges Basin Reservoir. Such water would be convertible to M&I purposes (as
specified in the Colorado Ute Indian Water Rights Senlement .Act) and depletions as specified in Ihe Colorado
Ute Indian Water Rights Settlement Agreement.
Z Project irrigation supplies take into account Project shortages which apply to irregular interruptions of
service based upon available water.
3 Retum flows and reservoir evaporation constitute the diHerence between supply and depletion.

on the Animas River as identified in the Settlement Agreement. Use of water by the Ute
Tribes would follow additional appropriate NEPA compliance. Reclamation would
participate and/or assist in the subsequent NEPA compliance, as appropriate.

! .

When fully operational and under full Project demand, 80,100 acre-feet of diversion,
either from Durango Pumping Plant or directly from the Animas and San Juan Rivers,
would take place. Return flows from M&\ use would occur in the Animas, San Juan, and
La Plata Rivers. An average annual depletion of 57,100 acre-feet to the San Juan River
would occur, meeting the conditions of the RP A.
