A breach in a PG&E-operated canal turned a Northern California creek bright orange last week. PG&E discovered a breach in the Butte Canal that was sending orange sediment spilling into the waters of Butte Creek on Aug. 10, PG&E spokesperson Paul Moreno told SFGATE. Upon finding the breach, the utility company opened a side spill gate upstream in order to stop water flowing to the canal.  State and federal resource agencies were then notified after PG&E identified turbidity in the creek, Moreno said. … A survey from the California Department of Fish and Wildlife is needed to determine whether the effects of the breach have affected salmon mortality, Moreno said.
