Project Description

In the wake of recent failure of the Oroville Dam Spillway, the Division of Safety of Dams (California Department of Water Resources) is requiring owners of high hazard dams to conduct a comprehensive study of their spillways. PID has two spillways affected by this requirement: one each at Paradise Lake and Magalia Reservoir. Following the detailed analysis, PID will be required to make any required spillway repairs/upgrades that come to light as a result of the study.


Spending Plan (will be updated to reflect necessary spending as a result of study)
