SACRAMENTO, Calif. – The U.S. Army Corps of Engineers Sacramento District is continuing construction to realign Avenue 146 and widen the existing Tule River Spillway at Success Lake in Porterville, California.

Avenue 146, including the Rocky Hill Recreation Area remains closed to all public foot traffic and vehicle access until further notice, due to the ongoing spillway enlargement project. The Rocky Hill closure includes day use arbors, boat launch ramp, and construction site shoreline. Tule Recreation Area boat launches on the east side of the lake remain open.

The Avenue 146 realignment will reduce road closures during high-water encroachment and provide access for future project work, including construction of a 10-foot-high Ogee Weir across the spillway, and armoring of both the Frazier Dike and the Highway 190 bridge that passes over the lake.

The project is expected to be complete in 2023, and will increase storage capacity in Success Lake by 28,000 acre-feet as well as help improve flood risk reduction for the region.

Schafer Dam and Success Lake, which was constructed by USACE in 1961, is operated by USACE 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.
