Waterways facilities

We provide one of the premier boating programs in the country.

  • 82 state-sponsored harbors (19 state-managed harbors and 63 local state-sponsored harbors of refuge).
  • 1,300-plus state and local boating access sites.
  • two state lock/dam systems owned and administered by DNR.
  • 6,000-plus boat slips spread across state and local harbors.

The Waterways Program

Derived from boat registration fees and the Michigan marine fuel tax, the Waterways Program helps fund the construction, operation and maintenance of public recreational boating facilities.

  • The program supports state-administered harbors along the Great Lakes and state-administered boating access sites on the Great Lakes and inland waters.
  • The grant-in-aid program provides grants to local government for harbors along the Great Lakes and boating access sites throughout Michigan.

Waterways Commission

The Michigan State Waterways Commission is a seven-member advisory board that works with the Department of Natural Resources on the use of dedicated funds, provided by boaters, for the acquisition, development and maintenance of public harbors and boating access sites, as well as certain locks and dams.

Key project updates

  • Two key boating access sites on Old Mission Peninsula – East Arm and Bowers Harbor – will receive significant upgrades, including paving. These improvements will enhance public recreational boating opportunities in the Grand Traverse area. Construction is anticipated in 2025. Details can be found below.

  • In September 2023, a fire at the Great Lakes Tissue plant led to the shutdown of the plant’s hydroelectric generator. The Great Lakes Tissue hydroelectric facility played a key role in water level management through “fine-tuned” incremental adjustments to water levels. Without these adjustments, the DNR must exclusively use the six gates at the Cheboygan Dam to manage water levels. 

    Beginning Oct. 15, the Inland Waterway will undergo its seasonal drawdown. Water levels in the Inland Waterway, especially in areas along the Cheboygan River and Mullet Lake, will decrease by approximately 12 inches until March 31. This allows for better management during spring thaw and runoff. Water levels will then be replenished starting April 1, with the goal of reaching the target lake level of 593.1 feet by April 15, depending on weather conditions. In the summer, lake residents and boaters along the Inland Waterway may experience larger water level fluctuations.

Waterways Facilities Assessment

In 2020, the DNR completed a Waterways Facilities Assessment of several state-sponsored (state and local grant-in-aid) harbors, boating access sites and two lock/dam facilities. This effort culminated in a report that includes facility infrastructure data, cost analysis, trends, and facility operation and development recommendations. This report provides guidance on funding, design, and operations.
