Grayhaven State Harbor is now under DNR management. As we begin the process of assessing and operating the harbor, please take note of the following updates for the 2026 season. Reservations for transient slips will open March 15 via MiDNRReservations.com; however, please be advised that these slips will not offer electrical service this season due to ongoing site assessments. While all current seasonal slip holders have been contacted, those interested in joining the seasonal slip waitlist can call 313-498-6695. Additionally, we're pleased to offer dedicated dockage throughout the month of April specifically for anglers. To secure a fishing dock for the month, please call 313-498-6695.
