Irvine Lake Fishing
Irvine Lake is open for shoreline fishing only. Bass, catfish, carp, bluegill, crappie and sturgeon are among the fish found in the lake. California Department of Fish and Wildlife regulations regarding fish limits apply even though a fishing license is not currently required at Irvine Lake.
Fishing conditions, shoreline access and operating rules can change with water levels, weather and construction activity. Check the official OC Parks Irvine Lake page before visiting.
Irvine Lake Dam Project & Upcoming Closure
Irvine Ranch Water District is preparing for a major rehabilitation of Santiago Creek Dam, which forms Irvine Lake. Preparatory work began in 2026, including modifications that will allow IRWD to draw the lake down as low as possible before major dam construction. Current plans call for the construction phase to run from 2027 through approximately 2030.
The project will replace the aging outlet tower and spillway, strengthen the earthen dam, improve seismic safety and restore reservoir storage capacity. Irvine Lake remains open for shoreline fishing at this time, but recreational access is expected to be affected as the project progresses.

About Irvine Lake
Irvine Lake was formed by Santiago Creek Dam, which was completed in 1933. Although the lake is well known for fishing and recreation, its primary purpose is water storage. Water from Irvine Lake supports regional water supplies, including the Baker and Howiler treatment plants, which collectively serve tens of thousands of homes in Central and Southern Orange County.
Serrano Water District, which serves Villa Park and a portion of Orange, historically owned 25% of Irvine Lake and Santiago Creek Dam. On January 15, 2025, Serrano transferred its ownership interest in the lake and dam to Irvine Ranch Water District. Serrano continues to include purchased local surface water from Irvine Lake as part of its water supply.
Irvine Lake History
Irvine Lake has a long history as an Orange County fishing and recreation destination. Public fishing dates to the 1940s, and the lake once offered boating, camping, a children’s fishing lagoon and other recreational activities in addition to fishing.
The lake closed to public fishing in March 2016 following disagreements involving recreational rights and lake operations. After several years of negotiations, Orange County and the other parties reached an agreement in 2019 that allowed public shoreline fishing to return.
Irvine Lake reopened for shoreline fishing on August 17, 2019. The current recreation program remains focused on shoreline fishing rather than boating, swimming, camping or other forms of lake recreation.
