Most drivers on Malibu Canyon Road pass right by the hulking, useless 100-foot-tall dam without even realizing it’s there. But if they pulled off onto the right turnout, walked about 15 feet and peered over the edge, they’d glimpse it: a huge gray dam entirely filled with sediment. … [Russell] Marlow compared Malibu’s Rindge Dam to the four Klamath dams on the northern edge of California, which were finally dismantled this year in the world’s largest dam removal project. It wasn’t easy; the Klamath dams only came down after decades of advocacy by tribal communities. Those dams caused the decline of Chinook salmon, by degrading water quality and blocking migratory routes. Like the Klamath dams, the Rindge Dam has caused decades of negative impacts to fish like the Southern California steelhead, plus other impacts to the broader watershed.
