Ridges Basin Contents - 450 cfs Supply Scenario
2 -Month Pumping Preference
Year -Round Pumping - May -June Pumping Only - May -June Pumping then Year -Round at 60,000 AF ..... Inactive Pool
Analysis: 450 cfs waleF— Aghtdiversion limit, with 2 -month pumping preference. When the reservoir Formatted: Font: Bold
level drops to near 60,000 acre -feet, allow year -round pumping until the reservoir significantly recovers
(above 100,000 acre -feet)
"ttle ampai#_ This w-c beca-61se when FeseFVG*F is GIFIGIpping, available FiveF water is FAWFAM
Observations: -- --
• With a 450 cfs wateF Fegkttdiversion limit, the content is below the dead pool level only 1 month
(March) in the analysis period with the 2 -month pumping preference then year -round when
level drops to near 60,000 acre -feet. Full project demands can be met.
• With a 450 cfs wateF F gWiversion limit. a 2 -month pumping cycle can occur 80 percent of the
time. 20 percent of analysis years would require year -round pumping.
