Just months after California’s deadliest wildfire laid waste to the town of Paradise, hillside residents face yet another costly and potentially dangerous problem. State safety officials have downgraded the Magalia Dam on the hill above town to “poor” condition, and have ordered the dam’s owner to make interim repairs by November on the cracked spillway. It’s the latest in problem for the Paradise Irrigation District, which lost most of its revenue base in the Camp Fire and is still struggling to deliver potable water to its remaining customers. The fire tainted the district’s water supply with the chemical compound benzene, forcing almost all of the few thousand people who’ve returned to Paradise to drink bottled water.
