In 1972, citizens of the city voted to rename it Lake Elsinore. More than a week of heavy rains in 1980 flooded the lake, destroying surrounding homes and businesses. Since then, a multimillion-dollar project has been put into place to maintain the water supply at a consistent level, allowing for homes to be built close to the lake. Overflow water in the Lake spills out via Alberhill Creek, a tributary of Temescal Creek. In 2007, an aeration system was added to help with the lake's ecosystem.
