SUSI'INA HYDRoELEC1'RIC PROJECT INSTREAM ICE SIMUlATION S1UDY FINAL REPORT,OCTOBER 1984 OOCUMENT NO.1986 ERRATA TEXT a)Section 3.3,first paragraph,4th sentence should read,liThe maximum upstream extent of the ice front ranges from River Mile 126 (1976-77 winter)to River Mile 140 (1971-72 winter)." b)Section 3.3,third paragraph should read,liThe mildest simulated riv-er ice conditions for the 1996 energy demand occur for the winter of 1976- 77 (Exhibit G).Maximum total ice thicknesses for this simulation range from 1 ft.to 6 ft.,of which 1 ft.is solid ice.These thicknesses exist downstream of River Mile 126 and are generally similar to those of natural 1976-77 conditions in the same reach.However,the maximum with-project river stages in this reach are 2 ft.to 7 ft.higher than natural conditions due to the higher with-project winter flaws.MaxilnUID river stages for the 1976-77 with-project simulation are 1 ft.to 8 ft. lawer than those of the 1971-72 simulation.II c)Section 3.3,fourth paragraph,fourth sentence should read,"Maximum extent of the ice cover with the warm releases is River Mile 126,versus River Mile 140 with inflow-matching release te:rrperatures." d)section 3.5,first paragraph,second sentence should read,"Results shaw that the beginning of the ice front progression at the Chulitna con- fluence ranges from early December to early January,approximately 0-2 weeks later than the corresponding Watana-only simulations,and 4-7 weeks later than natural conditons for the same winters." e)Section 3.5,first paragraph,third sentence should read,"Maximum upstream extent of the ice front ranges from River Mile 123 to 137,and is 2-13 miles downstream of that with Watana only and 1996 energy demand.II Section 3.5,third paragraph,fourth sentence should read,"Maximum river stages,where an ice cover exists,are 1 ft.to 6 ft.higher than corresponding natural conditions.1I Section 4.0,item number one,first sentence should read,"Relative to natural conditions,initial progression of the Middle Susitna ice front at the Chulitna confluence (River Mile 98.6)is expected to be delayed by 2 to 6 weeks with Watana operating alone,and 4 to 7 weeks with Watana and Devil Canyon operating together." - - -.
