Document Description
The California Department of Fish and Wildlife’s (CDFW) Hot Creek Hatchery is located on Los Angeles Department of Water and Power (LADWP) and Inyo National Forest owned property. As part of the Hatchery’s National Pollution Discharge Elimination System permit requirements, CDFW routinely collects water quality samples from the springs and discharge effluent to ensure compliance with the permit conditions. CDFW has been required by the RWQCB to develop a Groundwater Monitoring Program which includes the installation of monitoring wells and the collection of water quality samples from these observation points. The intent of the Groundwater Monitoring Program will be to establish baseline groundwater level and water quality parameters in the shallow aquifer system near the hatchery and to help identify any potential impacts associated with the percolation ponds and/or other point sources upgradient of the hatchery. This project will include the installation of four groundwater monitoring wells with 2-inch casing, estimated to be required no deeper than 100 feet below ground surface.
