CANNON SYRACUSE CAUSEWAY - A site has been selected for the building of a test section of Bountiful Boun-tiful architect Don Johnson's prestressed concrete diking proposal. pro-posal. The test site is approximately 1 12 miles from the Syracuse guard house on the Syracuse causeway dike. The test is scheduled to consist con-sist of approximately 20 precast concrete sections each 4 meters wide. The test section will be 40 meters long and 30 meters wide. The nan-drails nan-drails on the test section will provide pro-vide wave protection to 4,218 feet above sea level on the Great Salt Lake side. The record level of the lake reached approximately 4,212 in 1986. At 4,218 the test section would provide protection up to a lake level of 4,212. This would allow for a two foot wind tide with four foot waves. Even though the dikes to Antelope Island have been partially washed out, a good portion of the Jordan River is diverted by a canal to the western side of the Great Salt Lake. This is done to prevent the Farmington Bay area from becom-ming becom-ming too fresh. Even so, there is still a positive flow of water out of Farmington Bay over and through the dikes, and this arm of the lake is still fresher than the rest of the Great Salt Lake. The freshwater Farmington Lake proposal would entail the rebuilding of the existing causeway dikes to Antelope Island. Even though the dikes have been Washed out, much of the water from the Jordan River is currently diverted to the western side of the Great Salt Lake to prevent Farmington Farm-ington Bay from becoming too fresh. |
