The project consists of the construction of a series of gravity-fed ponds with islands and areas of varying water depths that will serve as fish and avian habitat, the development of associated water delivery systems, and associated electrical power infrastructure development to provide power for the water pump(s). These ponds will impound saline water at a shallow depth within the project site to create piscivorous bird habitat within an area of currently exposed and dry playa area. This will be done to offset the loss of habitat of this type that is occurring as the Salton Sea recedes and becomes increasingly saline. The SCH project will involve the construction of ponds to the east and west of the New River. These ponds will cover a minimum of 3,770 acres and will also be associated with water delivery and electrical power supply infrastructure. The Amendment revises the project description by changing the freshwater intake from a pump to a water diversion structure, adding a flood buffer zone, temporary river crossing, and temporary water diversion within the existing project footprint, and changing details of the design of the saline water channel, sedimentation basins, vista point, and boat ramps.
