FRISCHES HAFF  , a

lagoon on the Baltic coast of Germany, within the provinces East and West Prussia, between Danzig and Konigsberg . It is 52 M. in length, from 4 to 12 M. broad, 332 sq. in. in area, and is separated from the Baltic by a narrow spit or bank of land . This barrier was torn open by a storm in 151o, and the channel thus formed, now dredged out to a depth of 22 ft., affords a navigable passage for vessels . Into the Haff flow the Nogat, the Elbing, the Passarge, the Pregel and the Frisching, from the last of which the name Frisches Haff probably arose .
