SUMMARY Reach 3 of the Alpine Aqueduct and Reach 4 of the Jordan Aqueduct are complete with the exception of some landscaping and cleanup activities. Reach 2 of the Alpine Aqueduct is scheduled for completion during 1987. Facilities have also been constructed at the mouth of Provo Canyon to provide the capability of exchanging water between the Salt Lake Aqueduct (constructed in 1951 as part of the Provo River Project) and the Jordan Aqueduct. This exchange provides the M&I System the capability of being used in harmony with the features of the Provo River Project to deliver water to both the east and west sides of Jordan Valley as needs require. Jordanelle Dam and associated road relocations are undergoing spe- cifications design. A brief outline of the construction schedule for these remaining activities is shown in the following table. Construction schedu le Beginning Spring 1987 Spring 1987 Activity Acquisition of rights-of-way Relocate U.S. Highway 40 Final concrete surfacing Construct county road Relocate U.S. Highway 189 Construct Jordanelle Dam Stage rl./ Summer 1987 Summer 1989 Sta e II]) Fall 1989 S rin 1992 1 Stage I will consist of excavation in the dam abutments located on the right and left of existing Highway 40 by stripping surface mate- rial down to bedrock, initiating embankment construction in the flood plain area of the dam, and processing and stockpiling sand and gravel filter materials for both Stage I and Stage II. 2/ Stage II will constitute placement of the remaining dam mate- rials :- Fall 1987 Fall 1987 Complete Spring 1990 Fall 1989 Fall 1991 Fall 1989 Fall 1989 Need for Project Modifications Activities in the preceding update do not constitute significant modifications to the project requiring additional NEPA compliance. The need for significant project modifications that do require NEPA compliance are centered in six ba~ic areas: changing the road reloca- tions to accommodate public safety concerns; changing the location of the outlet works based on recent geologic findings; modifying the reser- voir management boundary to accommodate the'proposed road relocations and to accommodate proposed actions to preserve water quality in the poten- tial Jordanelle Reservoir; modifying the fishery mitigation/recreation plan for the Provo River below Jordanelle Dam in order for Reclamation to meet its mitigation commitments and in response to local concerns; adjusting the wildlife mitigation plan as a result of expected impacts of the above proposed modifications; and developing a plan to mitigate wetland and riparian habitat losses (not included in the FES).
