|Visitors to Lake Berryessa are being asked to help protect historic resources by not handling, removing or destroying any artifacts or ruins along the lake bed. Structures in the Berryessa Valley were removed or razed prior to the creation of Lake Berryessa, however the remains of historic sites, including farms, ranches and portions of the town of Monticello may be exposed as reservoir levels continue to lower. These sites and artifacts are protected by both federal and state laws that prohibit disturbing the sites in any way, including removing or relocating artifacts. In addition, the use of metal detectors is not allowed on Reclamation lands per 43 CFR 423.29(f). Please report any found ruins or artifacts, or any destruction or removal of ruins or artifacts to the Lake Berryessa Field Office at 707-966-2111.
