About Kevich Lighthouse

This round, white tower stands 15 meters tall, with a black lantern and gallery. Built in 1981, it first began operation that same year. The light emits a white flash with a four-second duration, followed by four seconds of darkness, a cycle created by a rotating shield around its bulbs. It is situated on a bluff overlooking the water. This structure is believed to be one of the few privately owned lighthouses remaining in the United States.

Why it matters: The Kevich Light is listed on U.S. Coast Guard navigation maps and is the second highest light on Lake Michigan.

Background
The Kevich Light is a lighthouse located in the town of Grafton, Wisconsin. This lighthouse was built privately by a person who has a general interest in lighthouses. It is built on the former site of the unincorporated community of Ulao, Wisconsin. It is listed on the USCG navigation maps as a private light. In 1990 it was officially registered as a United States Coast Guard Class II Private Aid Light. It is listed as light no. 20765. The light sits on a bluff and is 120 feet (37 m) above the lake level, making it the second highest light on Lake Michigan. Its 1,000 and 400 watt bulbs are surrounded by a rotating shield, resulting in four seconds of light, and then four seconds of darkness. Kevich Light is believed to be one of the last few privately owned lights in the entire United States.
