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)
|Project Phase||Previous Fiscal Year Expenses||Fiscal Year 15/16||Fiscal Year 16/17||Fiscal Year 17/18||Fiscal Year 18/19||Fiscal Year 19/20||Total|
PID's board considered these alternatives:
There are no alternatives; the California Department of Water Resources, Division of Safety of Dams, requires this study of PID.
Benefits to PID and its Customers
Increased spillway safety.
