Accordingly, a short wooden tower was constructed at the end of the north pier, equipped with a fourth-order Fresnel lens.

[2] In 1930 the Milwaukee Electric Railway & Light Company decided to build a $30 million steam-electric power plant south of the old shipping channel.

[4] In 1931 funds were provided to improve the harbor under the Works Progress Administration; Construction was protracted and the new breakwaters took three years to complete.

This light, constructed of steel plates in an Art Deco style, stood on an open concrete platform which in turn perched at the end of the breakwater forming the northern limit of the harbor.

The old lens and its lantern were removed at an undetermined date,[5] but keepers continued to operate the fog signal manually until 1975.
