Boat Ramps: The City of Port Huron also operates and maintains two boat launch locations; one at 12th Street and the other on Riverside Drive. A seasonal permit or a daily launch fee receipt is required for the use of these facilities from May 1 through October 31. Launch fees are in accordance with the MDNR Waterways Commission. The daily launch fee is $6.00 and instructions for payment are posted at each site. Seasonal permits are available through the Treasurer�s Office, and other locations, see details. They cost $24.00 and may be used for both launch sites. Proceeds from permit sales are used exclusively for maintenance and improvements to the boat launches. Trailered vehicles without a daily launch fee receipt or seasonal permit will be subject to civil infraction tickets in the amount of $50.00. The boat ramps and docks are installed in early spring when the fishing season begins. Boat ramps go in by the first of April. Docks are in by the first of May. Ramps and docks stay in, weather permitting, until approximately mid-November.
