Kurisches Haff, a fresh-water lagoon of East Prussia, extending 61 miles south from Memel; width in the south, 28 miles; average width, 14 miles. It is connected with the Baltic by the 'Memel Deeps,' a channel about 500 yards wide and 20 feet deep. The spit of sand-dunes, one to two miles wide, that separates it from the Baltic, is encroaching on the haff at the rate of eighteen feet annually.
