State water officials at Lake Oroville have supplied a dust-control plan to air quality officials after asbestos was detected at the work site this week. During recent air quality and sediment testing at the site, naturally occurring asbestos was found in some areas of the construction zone. Meanwhile, in a new test of the dam's battered infrastructure, the fractured main spillway was set to resume outflows today after a three-week shutdown.

Chapman University

A statewide study on the communication campaigns to conserve water during the drought has found that the messaging produced the exact opposite results intended. "What we learned was counterintuitive to what we expected," said Jake Liang, Ph.D., lead author on the study. "Conservation campaigns, regardless of the strategy – in general – led to participants having an attitude change in a negative direction—meaning they were less inclined to take action to conserve water after seeing the messages."
