on the lakeside of the structure.

A 2,000-ft-long south entrance arm breakwater (Figure 265, Section

and had a

50 percent being 5 tons or more.

A portion of the Old Breakwater was removed, resulting in a 982-ft

gap for a new entrance channel (Figure 265). A 1,800-ft-long rubble-
mound west breakwater (Figure 265) with a concrete cap was con-
structed to provide wave protection to the new entrance. The

A major storm occurred in January with wind gusts reaching 75 mph,

resulting in extraordinary sized storm waves. An inspection of the
harbor breakwaters subsequent to the storm revealed damages to about

1983-
Recommended repairs with stone and concrete to about 300 ft north of
the breakwater were completed for a cost of about 0,000. New
