Frequently Asked Questions About Potholes Reservoir Boating

Essential navigation guidelines, ramp rules, speed limits, and cold water hazards for Potholes Reservoir

What are the typical wind and surface wave thresholds for boating on Potholes Reservoir?

On Potholes Reservoir, wind speeds under 10 mph generally produce glassy to light ripple conditions optimal for all recreational craft, including pontoons and bowriders. Winds between 10 and 15 mph generate moderate freshwater chop (1–2 ft waves), while sustained winds exceeding 15 mph or gusts above 20 mph produce steep wind chop and whitecaps requiring vigilance, particularly for vessels under 20 feet. Current observations report wind at 7 mph with gusts to 12 mph.

Where can I launch a boat on Potholes Reservoir?

Public boat launch facilities on Potholes Reservoir are managed under Washington Parks & Wildlife jurisdiction. Check with local park offices for seasonal ramp water depths, gate hours, and launch permit requirements.

What are the navigation rules and speed limits on Potholes Reservoir?

Under Washington boating statutes and U.S. Coast Guard navigation rules, power-driven vessels must observe a 5 mph flat-wake speed limit within 100 to 200 feet of shorelines, designated swim zones, marinas, and moored craft. Children under 13 must wear an approved USCG Type I, II, or III life jacket while underway on recreational vessels.

Are aquatic invasive species (AIS) inspections required at Potholes Reservoir?

Boaters on Potholes Reservoir are required to follow mandatory Clean, Drain, and Dry biosecurity protocols. All drain plugs must be pulled and livewells drained prior to transport to prevent the spread of invasive quagga and zebra mussels, curly-leaf pondweed, and other aquatic hitchhikers.

Is cold water shock a risk for boaters and paddlers on Potholes Reservoir?

Water temperatures on Potholes Reservoir vary seasonally. In spring and early summer, snowmelt and deep thermoclines can keep waters dangerously cold even on warm sunny days. Always dress for possible water immersion and secure an approved life jacket.
