St Francis Dam Disaster Presentation

A car passed by the St. Francis Dam on the way to Powerhouse 1 on March 12, 1928. The driver saw a torch light at the base of the dam, and figured the dam keeper, Tony Harnischfeger was down at the base of the dam. A little while later, a motorcycle passed by the St. Francis dam just before midnight. The driver, Ace Hopewell, glanced over to the dam as he passed. All was calm. One can imagine how beautiful it was in the moonlight, giving off a white glow. He continued on his way to Powerhouse 1, where his shift began at midnight. A few minutes later, he heard a terrible crash. He stopped his motorcycle, smoked a cigarette and listened to the loud crashing sound. The area was known for landslides in the area….the Pelona Schist was unstable and often collapsed on to the road. He listened until the sound began to subside, and carefully, he continued on to work, looking for fallen rock. It wasn’t until he arrived at Powerhouse 1, that he was told that the St. Francis Dam had gone out. He was the last living person to see the dam intact.

Join the Historic Highway 99 Association of California on Tuesday, October 5 at 6:30 pm, for the story of the St. Francis Dam, the 2nd largest tragedy in California as far as loss of life. Presented by the St Francis Dam National Memorial Foundation.

US 6 / US 99 Interchange in 1955. Courtesy – Caltrans

In 1955, the first section of the Golden State Freeway opened. It was a short section, running from near Weldon Summit to Foothill Blvd. The freeway was the first major attempt to improve traffic in the Newhall Pass area and it did help for a time. The freeway remained until the early 1970’s when the new I-5 / State 14 interchange was constructed and the old freeway was reconfigured to become the “Truck Lanes”.

Today, the original interchange still remains, though not entirely used. The lower level, formerly the US 6 West to US 99 South connector, is now partially filled in. The second level still carries Sierra Highway with the top level carrying the I-5 Truck Lanes. The Newhall Pass has undergone many changes in its time as a transportation corridor for Los Angeles. This one was but one of those. The photo was taken on November 22, 1955.

This map of the Lake Elsinore area comes to us from San Diego County dating from November 1883. At the time, Elsinore was a part of San Diego County. In 1893, this area became a part of Riverside County.
