Canyon Lake became a city around a reservoir and a retreat idea
Canyon Lake's story runs through Railroad Canyon, a San Jacinto River dam, a recreation community, and cityhood in 1990.
Canyon Lake is unusual because the lake, the roads, the gates, and the city story are all tied together. It sits between Lake Elsinore and Sun City, and the community grew around Railroad Canyon Lake, a reservoir on the San Jacinto River.
The water story came first. Temescal Water Company planned a dam after old water supplies became less useful. Construction started in 1927 and finished in 1929. The lake slowly filled after winter rains returned.
The railroad part of the name is not decoration. A California Southern Railroad line once ran along the river. Floods in 1884, 1916, and 1927 washed out the tracks, and the railroad line was later abandoned. The water company bought parts of the old right-of-way while building the dam.
Later, developers pictured the area as a weekend retreat and recreation community. In December 1990, Canyon Lake became a city. That is the local twist: a water project and a getaway idea slowly turned into a fully governed city.
