When it comes to Oroville Dam, the state Department of Water Resources has been anything but forthcoming in response to California Public Records Act requests. Chico-based advocacy nonprofit AquAlliance sued DWR for documentation relating to asbestos that may have been uncovered during a break in the main spillway (see “Dam records sought,” Downstroke, June 15). Meanwhile, DWR has stymied area media, stalling in many cases and blacking out large sections of documents the agency does release.
