LAKE ISABELLA, Calif. (Oct. 21, 2009) - Tony Kittner, Isabella Dam project geologist, Sacramento District geotechnical engineering branch, demonstrates the crumbly consistency of the bedrock found 100 feet below the auxiliary dam at Isabella Lake. The loose rock was taken from core samples drilled nearly 300 feet beneath the dam, and differs dramatically from the solid granite bedrock found beneath the lake's main dam.
