C. Review of Guidelines
Beginning no later than December 31, 2020, the Secretary shall initiate a formal
review for purposes of evaluating the effectiveness of these Guidelines. The
Secretary shall consult with the Basin States in initiating this review.
Section 10. California's Colorado River Water Use Plan Implementation Progress
The California agricultural (Palo Verde Irrigation District (PVID), Yuma Project Reservation
Division (YPRD), Imperial Irrigation District (IID), and Coachella Valley Water District
(CVWD)) usage plus 14,500 acre-feet of Present Perfected Right (PPR) use would need to be at
or below the following amounts at the end of the Year indicated in Years of Quantified Surplus
(for Decree accounting purposes all reductions must be within 25,000 acre-feet of the amounts
stated):
Benchmark Date Benchmark Quantity
Year (California Agricultural Usage
& 14,500 of of PPR Use in maf)
2009 3.53
2012 3.47
In the event that California has not reduced its use in amounts to equal the above Benchmark
Quantities, the surplus determinations under Sections 4.B.1 or 4.B.2 will be suspended and will
instead be based upon the 70R Strategy, for up to the remainder of the term of these Guidelines.
If however, California meets the missed Benchmark Quantity before the next Benchmark Date, or
after 2012, the surplus determinations under Sections 4.B.1 or 4.B.2 shall be reinstated as the
basis for the surplus determinations under the AOP for the next following Year(s).
Section 11. Authority
These Guidelines are issued pursuant to the authority vested in the Secretary by federal law,
including the Boulder Canyon Project Act of 1928 (28 Stat. 1057) (the "BCPA"), and the
Consolidated Decree and shall be used to implement Article III of the Criteria for the Coordinated
Long-Range Operation of Colorado River Reservoirs Pursuant to the Colorado River Basin
Project Act of September 30, 1968 (Pub. L. No. 90-537), amended March 21, 2005.
Section 12. Modeling and Data
The August 24-Month Study projections for the January 1 system storage and reservoir water
surface elevations, for the following Year, will be used to determine the applicability of these
Guidelines.
In preparation of the AOP, Reclamation will utilize the 24-Month Study and/or other modeling
methodologies appropriate for the determinations and findings necessary in the AOP.
