Glen Williams is a public boat ramp providing access to the Lower Crab Creek arm of Potholes Reservoir near Moses Lake. This access point is managed by the Washington Department of Fish and Wildlife and is open year-round, making it a convenient launch for kayakers, canoeists, and motorboaters. The site includes parking, a concrete boat ramp, and restroom facilities.
**Important Seasonal Considerations:** Water levels at Potholes Reservoir fluctuate significantly due to irrigation demands from the Columbia Basin Project, with notably low levels occurring during summer and fall months. Paddlers should be aware that the ramp may become inaccessible during these periods of reduced water. Recent improvements have been made to the launch facilities, including a steeper concrete ramp and new floating dock system to accommodate varying water conditions. Check current conditions before visiting, especially if planning a trip during late summer or early fall.
The site provides excellent access to Potholes Reservoir and the surrounding Columbia National Wildlife Refuge, a peaceful paddling area known for its vast, open landscape. The reservoir is part of the Columbia Basin Project and offers opportunities for wildlife viewing and exploration throughout the year.
