Starting Oct. 1, Valley Water will begin draining Anderson Reservoir to the lowest level using the existing outlet in response to an order by the Federal Energy Regulatory Commission (FERC) to reduce the risk to the public should Anderson Dam fail during a major earthquake.
Draining the reservoir is the first in a series of activities aimed at making the dam earthquake safe. Currently, if a catastrophic failure of Anderson Dam were to happen during the rainy season when the reservoir is full, an area extending more than 30 miles north to San Francisco Bay and 40 miles south to Monterey Bay could see disastrous flooding.
To keep the public safe during construction, Valley Water is closing many recreation areas around Anderson Dam and Reservoir for several years, until the dam is entirely replaced with a new dam. Consequently, starting Oct. 1, 2020, the following recreation areas will be closed:
- Toyon Group Picnic and Parking Areas; Serpentine Trail; Dam Crest
- Woodchoppers Flat
- Anderson Lake Park’s boating and fishing, boat and vehicle parking areas, and boat ramp; Coyote Road from the toe of the dam to the boat and vehicle parking areas; and Lakeview Trail is closed from the Anderson Launch Ramp parking lot trailhead to the westernmost junction with the Rancho Laguna Seca Trail.
- Fishing will be closed for the entire reservoir shoreline
The Live Oak Picnic Area will remain open to the public and can be accessed from Cochrane Road.
