WHITMORE LAKE WATER AT HIGH STAGE: "Highest in a number of years" is the way a Whitmore Lake resident yesterday described the water level at this resort town 10 miles north of Ann Arbor. This view, looking east, was taken on the south side of the lake along Shore Rd. and shows one of the cottages that is almost surrounded by water. There is no need for the diversion tunnel from Horseshoe Creek this year. Two years ago the tunnel outlet on the shore of Whitmore Lake was above the ground; now the water is over the top of the tunnel.
