Sampson's Pit offers a paved boat ramp on Lower Crab Creek near Moses Lake, providing access to the Potholes Reservoir system. This launch point is convenient for kayakers, canoeists, and small motorboats looking to explore the scenic desert waters of the Columbia Basin Project area. The site is open year-round, making it accessible across all seasons.
**Important Planning Note:** Water levels at Potholes Reservoir fluctuate seasonally due to irrigation demands, with significant drawdowns occurring during summer and fall months. Paddlers should check current water conditions before visiting, as the primitive ramp may become inaccessible during low water periods. The surrounding area includes the Columbia National Wildlife Refuge, known for its peaceful, expansive high desert landscape—ideal for wildlife viewing and quiet paddling. Plan accordingly for seasonal conditions and bring supplies, as amenities at this access point are limited.
