The Onamia Lake boat ramp in Onamia, Mille Lacs County provides public access for kayakers, canoeists, and motorboaters. This launch site can accommodate boats up to 12-18 feet in length, with no launch fees required. The ramp offers a straightforward entry point to explore the lake and nearby recreational opportunities.
**Important Note on Invasive Species:** Onamia Lake is known to contain zebra mussels and other aquatic invasive species. Before launching, inspect your boat, trailer, and equipment thoroughly—including propellers, anchor lines, bilge water, and any clinging dirt or debris. Drain all water from your vessel before leaving the lake and rinse equipment to prevent spreading invasives to other waterways.
The lake borders the Mille Lacs National Wildlife Refuge area, offering paddlers scenic surroundings and wildlife viewing opportunities.
