For 30 years, the Glen Lake Association’s (GLA) Boat Wash Operation has been the first line of defense against aquatic invasive species. Located on the north shore of Little Glen Lake at 7075 W. Day Forest Rd., the boat wash plays a crucial role in protecting the Glen Lake/Crystal River Watershed by stopping invasive species before they reach the water.
When the Boat Wash opened in 1995, it was the first of its kind in Michigan—a creative idea that has since become a model for lake protection efforts across the state. Every year since, the Boat Wash has prevented unwanted plants and organisms from hitching a ride into Glen Lake, safeguarding its iconic crystal-clear waters.
This season, through September, staff interviewed 3,686 boaters, washed 690 boats, and removed 26 aquatic plants—at least two of which were confirmed to be invasive Eurasian watermilfoil (EWM).
The continued operation of the Boat Wash is possible thanks to the generosity of donors who supported the “Keeping It Blue” Boat Wash Endowment Campaign. This community-led effort permanently endowed the Boat Wash—covering one of GLA’s largest annual expenses and marking the most significant fundraising achievement in our history. The endowment ensures that this vital service will continue protecting the watershed for generations to come.
Boat Wash Fall Hours
As fall arrives, boat washing remains just as important. In October, the Boat Wash is staffed on Fridays, Saturdays, and Sundays from 7 a.m. to 6 p.m.
The self-service power wash equipment will remain available daily through October 26, when the facility closes for the season.
Clean, Drain, Dry to Prevent Invasive Species
Remember to Clean, Drain, and Dry between waterbodies—it’s the law. Michigan law requires that a person remove all aquatic plants from watercraft, equipment, and trailers before placing them into Michigan waters.
CLEAN off visible aquatic plants, animals, and mud from all equipment before leaving the water access. Rinse equipment and boat hulls with high-pressure, hot water when possible. Use low-pressure, hot water (120°F) to rinse the interior compartments of boats, and flush the motor with hot water (120°F) for two minutes—or according to the owner’s manual.
DRAIN the motor, bilge, livewell, and any other water-containing devices before leaving the water access.
DRY everything for at least five days before reuse—or wipe all surfaces thoroughly with a towel.
For anglers, the additional step of DISPOSE is recommended:
DISPOSE of unwanted bait, worms, and fish parts in the trash. When keeping live bait, drain the bait container and replace the water with spring or dechlorinated tap water. Never dump live fish or other organisms from one waterbody into another.
Each clean-up helps keep the watershed clear and healthy. Together, we’re stopping invasive species—one wash at a time.
