State Parks workers were pulling cable up a launch ramp at Bidwell Marina Thursday because the water level in Lake Oroville is on the rise. March’s storms have brought the lake level up almost 13 feet since the start of the month, according to the Department of Water Resources website. As of 2 p.m. Thursday the surface was just over 738 feet above sea level, up almost 3 feet in the previous 24 hours.
