The Blythe boat ramp provides year-round access to Potholes Reservoir, a large impoundment created by O'Sullivan Dam as part of the Columbia Basin Project. This concrete launch is located near Othello in Grant County and serves paddlers, anglers, and recreational boaters exploring the reservoir and surrounding waterways. The site includes basic amenities with restrooms available.
**Important considerations for paddlers:** Water levels at Potholes Reservoir fluctuate significantly due to irrigation demands, with notably lower levels occurring during summer and fall months. During these periods, the primitive launch may become inaccessible, so it's advisable to check current water conditions before planning your trip. The reservoir is surrounded by the Desert Wildlife Recreation Area, which includes Winchester Reservoir, multiple wasteways, and numerous small ponds and marshes—offering additional paddling opportunities for those exploring the greater area.
