Very local in shallow water near small islands in the southern part of the lake. Occasional, small loose groups of plants, in water less than ~12 inches deepĀ and stranded just above water level (down ~18 inches from early season high mark, due to an extended drought). Coarse sand over sloping gabbro bedrock on the north side of a very shallowly submersed reef that connects two islands which are ~50 feet apart.
