CDFW is intending to execute a Streambed Alteration Agreement pursuant to Section 1602 of the Fish and Game Code (#1600-2019-0133-R5) to the project applicant, County of San Diego Department of Parks and Recreation. Project activities include dewatering, excavation, and grading silt and sediment to deepen the lake basins and provide retention basins. Following recontouring, both basins will be lined with bentonite clay up to one foot below the water level in the west basin and two feet below the water level in the east basin. A natural substrate will remain in the upper portions of each basin to support native wetland vegetation. The banks of the basins will be stabilized by the placement of a layer of cobble rock extending from the water line in the majority of the west basin and from two feet below the water line in the east basin, down to a depth of approximately five feet. Following construction, both basins will hold water to a depth of 10 feet, with the upper level of inundation occurring at an elevation of 394 feet above mean sea level. Work will be phased, with Phase 1 occurring in the east basin, followed by Phase 2 in the west basin. After construction, both lake basins will be revegetated with native wetland plants and the surrounding uplands areas will be revegetated with a combination of native trees and shrubs. The project will also install underwater features to provide shelter for fish.
