San Diego to Permanently Cut Lake Hodges Dam Spillway Amid El Niño Concerns
What happened
The City of San Diego announced a change to its plans for Hodges Dam at Lake Hodges. Instead of beginning a new dam as originally planned, the city will cut the existing dam’s spillway down to 280 feet permanently. This modification, which is called “interim risk reduction,” will cost $50 million and take seven years to complete, starting in 2030. The permanent cut means the lake can never rise above the state’s limit.
Why it matters
The permanent reduction in the reservoir’s capacity exposes 600 acres of lakebed, creating a fuel bed that increases wildfire risk in downstream communities like Ramona and Del Mar. Furthermore, the modification delays the construction of a new dam past 2035 and increases long-term risk liability for the City of San Diego.
El Niño is anticipated to bring significant water impacts to San Diego.
