Corps to discuss Success Dam enlargement project at Feb. 4 public meeting

Published Jan. 24, 2019

The U.S. Army Corps of Engineers Sacramento District will host a public meeting February 4 to discuss the re-initiation of the Tule River Spillway Enlargement Project, which received $74 million in appropriations in 2018 to raise Success Dam’s spillway up to 10 feet higher.

Previously known as the Success Reservoir Enlargement Project, the effort to reduce the flood risk to downstream communities such as Porterville, while also increasing reservoir storage, has been a stop-and-go effort as the Corps looked into potential deficiencies associated with Success Dam.  Now that those studies have concluded, the Corps is ready to re-start the enlargement project.

Success Dam provides flood risk management for the City of Porterville and surrounding communities. There is currently a 1-in-50 chance in any given year that flooding will occur in Porterville from Tule River flows. The spillway enlargement project is expected to further reduce that flood risk by nearly half.  Construction is scheduled to begin in 2022 and would be complete by 2024.

The public meeting is scheduled for Monday, Feb. 4, from 4 to 7:30 p.m. and will be an open house format, meaning there will be no formal presentation given. Attendees can arrive anytime during the meeting to get an overview of the project, view maps and conceptual designs for the enlarged spillway, and ask questions of Corps team members. Attendees can also submit public comments during the meeting. 

Success Dam and Lake, which was constructed by the Corps in 1961, is operated by the Corps for flood control and storage of irrigation water. Recreational facilities at the lake were added after the dam was completed. The dam is located on the Tule River about 6 miles east of the City of Porterville.
