Lake Superior water levels higher than normal



Large waves from Lake Superior tossed rocks, sticks and other types of debris onto the road next to the East Bay Suites last Friday, October 12. A couple stands with their cell phones in hand taking pictures of the ferocious waves. A large amount of rain also fell and filled the co-op parking lot with so much water that it took more than 24 hours to drain. Staff photos/Brian Larsen
