Dispersed camping near John Day Lock and Dam on Lake Umatilla provides riverside opportunities in a semi-arid climate typical of Oregon's Columbia Plateau region. The area receives approximately 10 inches of rainfall annually, creating a desert-like landscape with dramatic temperature fluctuations between seasons. Most dispersed sites sit at elevations between 200-400 feet along the Columbia River corridor.
What to do
Fishing access: At Three Mile Canyon Park, the proximity to the Columbia River provides excellent fishing opportunities. One camper noted, "We stayed here three nights and had a wonderful time. We were able to back in and view the Columbia river from our dinette window."
Hiking nearby: Forest Road 2730 in Mt. Hood National Forest offers hiking options within driving distance. A visitor shared, "There are several places along FR 2730 where you can pull off and camp. The road was very accessible, high clearance not required."
Photography: White River Crossing provides scenic riverside photo opportunities when water levels are appropriate. A review warns about access constraints: "BEWARE 4x4 required. Access Road in is super steep and rocky. Would not recommend coming out anytime other than summer!"
What campers like
Riverside positioning: At Avery Rec Area, visitors appreciate the waterfront access. A camper mentioned, "Can't beat a waterfront spot. So far no one else has shown up. It's about 6pm but been dark for an hour and half."
Convenience for travelers: Many sites serve as perfect overnight stops during longer journeys. One visitor at Three Mile Canyon Park commented, "The location and convenience is practically unbeatable. Was a great spot to rest and continue road-tripping the next day."
Solitude opportunities: Certain sites offer significant privacy during off-peak times. A camper at NF-3511 @ Mt Hood shared, "Past a few vans pulled over on the way up, But no one drove past me the entire night."
What you should know
Train noise considerations: Railroad proximity affects several camping areas along Lake Umatilla. At Avery Rec Area, one reviewer warns, "This place is free for a reason. It has actually nice location, but the trains are no joke. They are seriously loud do not underestimate this."
Weather impacts: Summer brings intense heat while winter conditions can limit access. A camper at White River Crossing advised, "Nice place to sit and dip your toes when it's hot though!"
Variable site conditions: Not all dispersed camping locations maintain consistent quality. One camper investigating Patterson Slough reported, "Went to check it out but it's a nasty old concrete slab with a no camping sign, a cruddy old boat ramp, and a nasty body of water."
Long-term occupants: Some sites have extended-stay campers. A visitor to Avery Rec Area observed, "Not many people, though some 'long-term' campers. The area is a bit messy as it is used for fishing net storage and old-boat storage, it seems."
Tips for camping with families
Bathroom availability: Select sites with toilet facilities for family convenience. At Rufus Landing, a camper noted, "1 pair of toilets available (His/Hers)."
Noise sensitivity: Consider children's sleep needs when selecting locations. Three Mile Canyon Park visitors mentioned asking neighbors to adjust: "Had to ask a group to turn down the music when trying to go to bed, which they did kindly."
Wildlife awareness: Some areas have specific wildlife considerations. A Three Mile Canyon Park camper mentioned, "Bathrooms did have toilet paper and warning signs about rattlesnakes but did not see or hear any, thankfully."
Tips from RVers
Generator etiquette: Follow generator protocols appropriate to each site. At Rufus Landing, a camper shared, "I ran the generator in my class c rv all night without a problem but made sure I was away from other campers. There is a rule that it cannot annoy other people."
Vehicle access limitations: Check road conditions before arrival with larger rigs. At Forest Rd 2730, a camper advised, "I parked nearest the access road, as my van would have hit trees to go a little further in. For smaller vehicles, you can get in a little further and off the access road."
Weather preparation: RVers should prepare for significant wind in the Columbia Gorge area. A visitor at Avery Rec Area commented, "Not hard to get to and literally right on the Columbia River but a bit too windy for kayaking unless you're a pro."
