About Irvine Lake

Irvine LakeIrvine Lake (known as Santiago Creek Reservoir) was formed by the Santiago Dam, built in 1931. It was constructed by The Irvine Company and Serrano Irrigation District (today known as the Serrano Water District). Irvine lake stores approximately 28,000 acre feet of water.  Originally the lake served the agricultural and farming communities surrounding Irvine Lake. Today the Serrano Water District provides drinking water to Villa Park and some parts of Orange.  IRWD uses untreated water from Irvine Lake to supplement its irrigation water and is able to treat water from the lake as part of the Baker Water Treatment Plant project. IRWD responsibilites are limited to these functions. We do not manage and are not responsible for any recreational activities.
