| Relation | Central Utah Project; Western Waters Digital Library; rhenn rcenn responses kee nee c to comment letter no 3 3.1 31 31 the lne lue PRRP will not cause any additional flooding of non project lands even during heavy spring runoff because the jordanelle Jor danelle reservoir storage and releases have been designed to accommodate the high spring runoff events mentioned in the comment reservoir storage has been sized to fully contain the volume generated from greater than a 100 year runoff event discharges from jordanelle Jor danelle reservoir outlet works and in extremely rare events spillway flows into the PRRP project area will be monitored by the bureau of reclamation as part of the normal operation and management of the reservoir for more detailed information please refer to the following the proposed action and existing channel modification alternative provide a minimum i i of 100 year flood protection as noted in the draft EIS chapter 1 section 13.2 132 132 paragraph 1 section 13.6 136 136 paragraph 1 section 172.3 1723 1723 and section 18.2 182 182 map A 9 in the draft EIS shows 2 year 10 loyear year and 100 year flood boundaries for the proposed action for the histream instrearn hi stream structures alternative no action alternative and baseline conditions the existing channel system provides channel and flood plain capacity flood easements for a minimum of the 100 year flood flow project design hydrology and impacts of jordanelle Jor danelle reservoir storage on peak flood flows are discussed fully in the PRRP draft water resources technical report section 3.4 34 34 3.2 32 32 changes in the flow regime that are proposed for the provo river below jordanelle Jor danelle dam are part of the baseline condition and will benefit most indigenous and sport fish species now that jordanelle jordanelie Jord Jor danelle anelie anelle dam is operational stream flow fluctuation will be less than in the past please refer to the PRRP draft aquatic resources technical report CUWCD CLIWCD 1996a section 32.3 323 323 and a base flow of 125 cfs cs will be released as part of the baseline conditions Irn impacts pacts of the baseline conditions and restoration alternati alternatives alternate es on fish resources are evaluated in chapter 3 sections 35.5 355 355 and 35.6 356 356 of the PRRP draft EIS and the PRRP draft aquatic resources technical report 3.3 33 33 two of the primary purposes of the provo river restoration project are to 1 increase the biological productivity and diversity and 2 rehabilitate and create a diversity of wetland and aquatic habitats to achieve these purposes it is necessary to increase wetlands the creation of wetland habitats will not only increase biological diversity but will provide essential habitat for species such as the spotted frog whos chos populations have greatly declined in recent decades active wetland creation will only occur on existing or acquired project lands 3.4 34 34 your comment addresses the minimum width of 50 feet for a public access corridor for public angler access along the provo river from jordanelle danelle Jor dam to deer creek reservoir the commitment for this corridor was made as part of the record of decision for the 1987 final supplement to the final environmental impact statement for the municipal and industrial system of the bonneville unit rather than as a component of the PRRP the 50 feet public access corridor is considered a baseline condition as described in the draft EIS chapter 3 section 31.2 312 312 please also see section 14.1 141 141 chapter 1 of the final EIS As is described in section 1.2 12 lt it of the final EIS the purposes and needs of the PRRP include the implementation of CUP and provo river pro project j ect act mitigation requirements over and above just the public angler access requirement of the 1987 mal mai final supplement these are fish habitat and riparian habitat improvements there has never been a limitation of 50 feet from the channel edge associated with meeting those environmental mitigation commitments section 1 1111 111.1 ilil iiii 11 1 in chapter 1 of the draft EIS described land use and ownership changes associated with the PRRP alternatives the proposed action requires a corridor of greater than 50 feet on each side of the proposed channel in some reaches to provide area for flood pa p1 plain and riparian habitat development to accommodate off channel features side channels ponds to avoid creating isolated islands of private ownership within the core area and to set aside an appropriate core area for potential minor channel migration the existing channel modification alternative could not be constructed completely within the baseline corridor either it would require an additional 22 acres of fee title andor easement acquisition to complete the instream instrearn In stream structures alternative could be constructed completely within the baseline corridor please see section 1.3 13 13 1 in chapter 1 of the final EIS for an overview of the proposed action and alternatives including land acquisition requirements 421 4 21 |
