. . USFWS - Palisade/Grand' Junction Stream Flow Analyses - DRAFT May 12, 1995 'Page 25 Mr. BQb McCabe of the Division Engineer's staff was contacted about the administration, travel times and travel losses of the reservoir releases from Ruedi Reservoir to the critical reach. Mr. McCabe said the State assesses a 10 percent conveyance loss on the releases. He said travel time varies depending on the river stage but it usually takes about 1 to 2 days. In the administration he allows the releases to be diverted by the power plant which then return the releases to the critical reach. Figure 13 shows the estimated affect the releases had on flows entering the critical reach. The Palisade gage flow without the releases was estimated by subtracting out the reservoir releases adjusted for a 10 percent loss and 2 day delay. 15 MILE - REACH INFLOWS Measured allhe Palisade Gage 1000 800 (f) LL 0 .5 600 <Jl ;;: 0 0:: E ro Q) '- - (f) 200 ---------------..--------------------------.. - .-----_. ,.-----------" ./" '-__________n___d ., o 15th July August September October 15th - Palisade Gage w Ruedi Rei - Ruedi Res.

Without the Ruedi Reservoir releases river flows would have dropped below an estimated 350 cfs. The above analysis assumes the releases were administered down to the critical reach. Additional data is needed to verify if releases actually made it to the critical reach or were they diverted by the irrigation companies. According to Mr. McCabe the deliveries
