Document Description
The Valley District proposes to annually recharge up to 30,000 acre feet per year (AFY) of State Water Project (SWP), or an average of 15,000 AFY based on water availability, in the Waterman Spreading Grounds in San Bernardino, which are owned and operated by the San Bernardino Flood Control District (SBCFCD). To facilitate the recharge, specific maintenance activities are required In 1 O of the 12 existing percolation basins in the Waterman Spreading Grounds (Proposed Project). Maintenance would generally be conducted in two cycles, one in the late winter/early spring and again in the late summer/early fall and would consist of removing vegetation and excess sediment, ripping/scraping the basin floors, and repair of various basin structures of only the areas of the basins in the Spreading Grounds that will be used for recharge.
