State inspections of California dams reveal that owners of the facilities have a pattern of delaying important maintenance, according to a Bee review of recent inspection records. The Bee reviewed five years of inspection reports by the California Department of Water Resources for 93 dams that the state identified as potentially problematic in the wake of the Oroville Dam spillway failure. All 93 dams are classified as high-hazard, which means that a dam failure could risk lives downstream. The state inspects 1,249 dams in California – federal dams such as Folsom and Shasta are not included.
