2.J. Senior Water - Water that flows through Vallecito for the benefit of water rights senior
to, and downstream from, the Vallecito water rights. Senior Water is not considered Donated
Water, nor is it charged by the CDWR against the fill of Vallecito.

2.K. Shortage-

a. A Shortage in the Summer Months is defined as (1) when Projections indicate
that Vallecito will not physically fill to 95,000 AF during the water year or, (2) Vallecito
has failed to achieve a physical fill of 100,000 AF during the water year, unless
Projections indicate that Vallecito will physically fill to 95,000 AF or more.

b. A Shortage in the Winter Months occurs when Projections indicate that Vallecito
will not physically fill to 95,000 AF during the water year.

2.L. Storage Water - Water physically stored in Vallecito under any priority, or water
released to the Pine River that CDWR considers as storable Vallecito inflow under any
priority that counts against Vallecito water rights, i.e. a paper fill of Vallecito.

2.M. Summer Months - May 10 through September 30

2.N. Winter Months - October 1 through May 9

2.0. Vallecito Deliveries - The term includes releases from Vallecito to supply
downstream water demands based on PRID and/or TRIBAL water agreements, both written
and unwritten, or Project delivery obligations for irrigation, domestic and other uses. Vallecito

Section 3
Amount of Donated Water Available to CWCS for ISF Use

All obligations of PRID and the TRIBE with regard to the provision of Donated Water
hereunder are conditioned by the following. If any of the following situations occur, PRID
and/or the TRIBE will notify the CWCB as soon as practicable of both the reduced amount of
Donated Water to be provided to the ISF Reach and the duration for such reduced amount:
(1) lack of Vallecito functionality for any reason; (2) an inability to fully meet Vallecito
Deliveries; (3) a Compact call on the Colorado River which requires releases from Vallecito;
or (4) a temporary emergency situation on the Pine River or for one or more of the Pine River
ditches that would require PRID to refrain from releasing or delivering water from Vallecito.
PRID and/or the TRIBE will notify CWCB of both the amount of the Donated Water to be
provided to the CWCB and the duration for the provision of such reduced amount

3.A. Winter Months

1.a. Beginning on October 1 of each year, for the Winter Months, if storage in
Vallecito is at the Highest Allowed Physical Winter Water Level or more, PRID and/or
the TRIBE shall provide Donated Water at the Measuring Point to CWCB to maintain
an amount equal to 50 cfs, or the inflow into Vallecito, whichever is less, to preserve
