Important Approach & Navigation Notes (Updated 2026)

The water depth on a raised shelf approximately 75 feet off the harbor entrance is approximately one-inch above the standard Chart Datum at about six-feet.  Vessels should approach the harbor directly from the West or Northwest ONLY.  Do NOT approach or depart South or Southwest, as this area contains hidden shoals & rocks, with unmarked water depths as shallow as 3-feet. The water depth at fuel dock is approximately 8-feet. Slip depths range from 7-feet to under 4-feet, based on slip location, subject to seasonal fluctuations. The Harbormaster will gladly provide up-to-date depth information upon request. Due to draft limitations within the harbor and the approach, we are unable to accommodate deep keel vessels within the marina.

The fuel dock is located at the south end of the main dock. Temporary tie-ups along the outer south perimeter dock and available with an "Hourly Fee" for quick day-visits to Ephraim.  Please contact the Harbormaster to check availability at (920) 854-4014 or via marine radio on Channel 9.  At this time, confirmation of your boat draft vs. the water depth on the south-wall can be confirmed.

Please also be aware of, and give right-of-way, to the small sailboats that frequently operate off the harbor entrance for sailing school activities, races, and regattas hosted by the adjacent Ephraim Yacht Club.  Please note and respect the white "No-Wake Markers" along the shoreline.

Eagle Harbor and the surrounding waters of Green Bay are known for rocky shorelines and shallow shoals. Boaters are strongly advised to consult current nautical charts, follow all U.S. Coast Guard buoys & markers, and navigate with caution—particularly near islands and unfamiliar shoreline areas throughout Door County.
