Show Study conducted plummernf the Upper &' be stitched acrose Colorado River to v measurements o verities and o prep Sf TheVation of Glen Canyon Dam will be restricted to 1,000 to 3,000 cubic feet per second (els) for a 4 hour period during the day to facilitate the study, "This work is being done as part of our assessment nf nrobable impacts of ad- (jjng aaaiuonai fceueraiing units to Glen Canyon Powerplant and of operating the plant for peaking power," Mr. Plummer said. "Fluctuations in river flow would be substantially greater than at present if these additions and changes were to be made." The habitat study will aquatic habitat in the river at various flow levels from 1,000 to about 26,000 cfs. From these measurements, habitat availability will be projected for flows up t0 40,000 cfs, which would be the maximum flow under a peaking power operation. Fishermen and boaters should be aware that the fishery habitat study win proceed every day of the week and will continue through the weekends during the March 3 - r period inilttM""""i |
