Through Nov. 21, people recreating near or in the lower McCloud River — the stretch between McCloud Dam and Lake Shasta — should watch for fast-flowing water and higher than normal water levels. Flows are about a foot higher on the lower McCloud River in northern Shasta County while Pacific Gas and Electric Company maintenance crews work on the James B. Black Powerhouse, the utility company said. That’s because PG&E won’t divert water from the McCloud Reservoir to Iron Canyon Reservoir and to the powerhouse while crews work in the area. As a result, the McCloud Reservoir filled and excess water is coming over the spillway into the lower McCloud River.
