Power Generation Narration
Geology Wickiup Dam and Reservoir are situated in forest covered volcanic mountains, consisting of buttes, craters and intervening sediment covered basins. The intermittent out-pouring of lava flows and explosive volcanic activity has created very complex geologic situations in local areas. The porous lava flows, breccia, ash and deposits of water lain sediment can be linked to a huge absorptive sponge with local perched or depressed water tables, where lakes and springs have been created at various elevations, according to the rate of inflow or outflow of water as it adjusts to local topographic and geologic conditions. The readjustments of the earth's crust during and following volcanic activity undoubtedly created huge cracks, fissures and faults through which the surface water can be lost or move to lower subsurface elevations
