Book excerpt: Excerpt from Effectiveness of Filling Ephemeral Pools at Kesterson Reservoir: Kesterson Program Upland Habitat Assessment; Kesterson Reservoir Final Cleanup Plan The State Water Resources Control Board, in Order No. Wq 88-7 issued July 5, 1988, directed the Bureau of Reclamation (Reclamation) to fill all ephemeral pool areas, on a priority basis, to six inches above the rising ground water by January 1, 1989.The objective of the Boards Order was to eliminate surface pools formed by rising ground water prior to the 1988-89 winter season. This report presents a summary of the filling activities at Kesterson Reservoir and an evaluation of the effectiveness of the filling in the elimination of ground water pools at the Reservoir. Description of Pilling Operation Contract Summary A letter contract was issued to Dutra Construction Co., Inc. of Rio Vista, California on July 6, 1988.The contract specified the filling of an estimated 589 acres with an estimated 723,400 cubic yards of material. Ephemeral pools were to be filled on a pond priority basis, with ponds 1, 3, 4, and 6 to be filled first, followed by ponds 5 and 7, and then the remainder of the ponds. The contract required completion of the scheduled work by December 1, 1988 and included incentive payments, based on volumes of material imported, for early completion of the work. As the work progressed, modifications were made to the original contract. When the contractor demonstrated that work could be completed by the scheduled deadline, the requirement for filling based on pond priority was eliminated and the contractor was allowed to place fill in the most efficient manner. A neighboring landowner requested that material be removed from his land to benefit his waterfowl management activities. After determination by the Fish and Wildlife Service and Reclamation that such borrow operation would benefit wildlife, that the material was suitable for use in the Reservoir, and that use would result in a cost savings to the Government, the contractor was allowed to use borrow material from this site. Modifications to the original contract were also made to provide for discing of 345 acres of cattails prior to filling, maintenance work on Gun Club Road, provision of a special bus to safely transport children to and from school, and revision of the quantity of material needed to complete filling of the Reservoir. Hauling of material was completed on November 16, 1988, and the contract was complete on December 16, 1988. Total contract costs were approximately 6.5 million dollars.
