ICE SPEAR FISHING: FOCUSING ON THE UPPER MISSISSIPPI LA CROSSE REACH Ron Deiss Clock Tower Building, P.O. Box 2004, U.S. Army Corps of Engineers, Rock Island District, Rock Island, Illinois 61204-2004 Ice spear fishing is one of the oldest, traditional methods for harvesting fish during the winter months. It has been practiced in the Upper Midwest Great Lakes region for over 1000 years. Ice spear fishing became popular in the La Crosse Reach on the Upper Mississippi River in the late 19th and early 20th centuries, but was completely prohibited by the late 1930s. During the height of its popularity, ice spear fishing in the La Crosse Reach adapted to the varying river conditions and developed a regional style.
