Power Generation Narration
Geology The Crooked River drains a mountainous area composed of volcanic tuff and agglomerate beds, and basalt, rhyolite and andesite lava flows ranging in age from early Eocene to Recent. The drainage basin exhibits a wide variety of topographic forms owing to variation in the resistance of volcanic beds and the varying degree of folding in the area. Depth of overburden at the damsite is not uniform. In the areas where bedrock exposures are common, overburden ranges from several feet deep.
