We need your help to keep it that way.

Boat Ramp Maintenance
The Boat Ramp is ready for 2016
Power Loading causes damage to launch ramps
"Power loading" is using the boat motor to load and unload a boat onto and off the trailer. The propeller wash creates a hole at the end of the ramp and a sand mound beyond the ramp. It creates hazardous conditions, and will cause time consuming and expensive ramp repairs.
Please – No Power Loading !

The DL Book Club meets at the Pellston Airport, 2nd floor, 10:30 a.m. each Wednesday.
