Electrical Power for Valdez and the Copper River Basin-1981

15. That the CE collect intragravel temperature data of Allison Creekcontinuously for at least one year, beginning as soon as possible.Response: Intragravel temperature data will be collected during theadvanced engineering and design phase.16. That the CE take temperature profiles of Allison Lake to the laketap depth and temperature, dissolved oxygen, turbidity, heavy metal, andpH readings at the lake surface as well as the depth of the lake tap.These measurements should be collected as soon as possible. A minimumsampling effort would include the months of March, June, September, andDecember.Response: Refer to response to number 15.17. That the.CE collect continuous temperature data below the proposedtailrace into Allison Creek for at least the first year of projectoperation.Response: The thermograph which is now operating in Allison Creek willcontinue to collect data for at least the first year after projectcompletion.18. That the CE determine the base flow in Allison Creek expected abovethe powerhouse after project op~ration.Response: Preliminary estimates have been completed and are included inthis report. A gage will be installed during AE&D and maintained afterproject completion.19. Response: An eagle nest survey will be.conducted prior to anyconstruction associated with the project.20. That provisions be included in advanced project planning forescapement survey of salmon in Allison Creek by the FWS or ADF&G.Response: ADF&G, has indicated they would increase their effort onAllison Creek. During AE&D at least one year of intensive an escapementsurvey will be conducted.21. That provisions be made in advanced project planning for instreamflow analysis of Allison Creek by the FWS to determine optimum flowschedules and the velocity of supplemental flows to Allison Creek.Response: Provisions for flow analysis of Allison Creek will be includedin the AE&D phase. Whether an extensive instream flow analysis isreqUired is not known at this time.
