BackgroundRoughly {{convert|2.5|mi|km}} downstream from the San Luis Dam, O'Neill Forebay collects irregular water releases from the San Luis Dam and William R. Gianelli Powerplant in its {{convert|56400|acre.ft|dam3|abbr=on}} basin. A morning-glory type spillway lies at the left bank of the reservoir. The reservoir is fed by the California Aqueduct and the Delta–Mendota Canal. Water from the canal is lifted a vertical distance of {{convert|8|ft|abbr=on}} into a channel running {{convert|2200|ft|abbr=on}} into the forebay.[1] O'Neill Dam{{main|O'Neill Dam}}O'Neill Dam, constructed from 1963 to 1967, is an {{convert|87.5|ft|abbr=on}}, earthfill and rockfill dam, stretching over {{convert|3|mi|abbr=on}} across the valley of San Luis Creek. With a maximum reservoir depth of {{convert|57|ft|abbr=on}}, peak inflow to the forebay is {{convert|15600|ft3|dam3|abbr=on}} per second, from both the San Luis Dam and the Delta–Mendota Canal. The drainage area of the reservoir downstream of the San Luis Dam is only {{convert|18|acre|dam2|abbr=on}}. The O'Neill Pumping-Generating Plant produces 28,000 kilowatts.[1] RecreationThe California Office of Environmental Health Hazard Assessment (OEHHA) has developed an advisory for O'Neill Forebay because of mercury and PCBs found in fish caught here. The advisory[2] provides safe eating advice for multiple fish species. The largest striped bass caught in California was caught in the O’Neill Forebay. The fish, {{convert|52.5|in|abbr=on}} and weighing {{convert|70.6|lb|abbr=on}}, was caught on August 5, 2008, by Frank Ualat of Gilroy, California.[3] See also
