Show reservoir would also develop a larger average annual municipal supply than the smaller reservoir, Dam heights for the smaller and larger capacities would be 320 feet and 1+ 20 feet, respectively. Embankment volumes would be 11,300,000 cubic yards and 28,780,000 cubic yards, respectively. Borrow areas would be required, but would mostly be within the reservoir basin. Relocation of U. S. Alternate 189 for 8.1 miles would be required, along with 3- 3 miles of 12.5- kv power line. Land to be acquired for these enlargements would be as follows: Potential Reservoir River Irrigated Brush summer home capacity bottom meadow Pasture pasture area ( acre- feet) ( acres) ( acres) ( acres) ( acres) ( acres) 155,000 70 510 280 420 2,260 320,000 110 650 Uoo 500 2,5^ 0 The length of Provo River inundated would be 7 miles for the smaller reservoir and 7.8 miles for the larger reservoir. The lower total estimated cost of Jordanelle Dam and Reservoir, as compared with that of Hailstone Dam and Reservoir, favors the Jordanelle plan. Recreational potential would also be greater at the Jordanelle site. ( e) Provo Bay Alternatives Alternative plans have been developed for the different features within the Provo Bay development area. Considered were location, size, and methods of separating the bay from the lake and then draining and irrigating the bay to make it useable for agricultural purposes as set forth in the proposed plan. Alternative locations for the Provo Bay Dike were studied to determine the optimum area to be diked. From these studies, it was determined that the dike would be constructed from Provo River on the north to Spanish Fork River on the south. Each of the alternative locations studied was designed to provide protection for the Provo Airport. The plan originally authorized for Provo Bay included all the land west of the Union Pacific Railroad ( UPRR) tracks. Subsequent to 615 |
