Irvine Lake is a reservoir in Orange County, California, United States.

Stocked with largemouth bass, catfish, trout, and crappie, the lake fishery opened to the public in 1941.

The land around the lake is owned by the Irvine Company, which leases the fishing, boating, and camping concessions to SWD Recreation Inc.[citation needed] The lake had not been full from 2011 onward due to an extended drought, and its levels had been steadily decreasing for years.

[1] By August 2019, the lake was naturally refilled due to an unusual amount of rain.

In August 2019, the lake was successfully reopened to the public for shore fishing and other activities after OC Parks, the Serrano Water District, and the Irvine Company came to a one-year agreement to resume operations.
