River conservationists on Wednesday urged state regulators to reassess how aging hydropower infrastructure is operated and maintained — and, in some cases, whether certain facilities should remain in place — following a 14-foot diameter, high-pressure water pipe ruptured last week. While praising the immediate emergency response of Yuba Water Agency and California Department of Fish and Wildlife, advocates said the rupture raises broader questions about how dams and related infrastructure are managed in California. … The incident, which took place about five miles downstream of New Bullards Bar Dam, led to the deaths of hundreds, possibly thousands, of juvenile salmon.
