Lucky 7 is a standing wave on the Colorado River near Palisade, Colorado, close to the Price-Stubb diversion dam just upstream of the I-70 bridge. It's described locally as the roller furthest from the highway, one of several waves that can form along this stretch of river. Like the rest of this reach, it's a spring and early-summer feature—waking up with snowmelt and losing shape as flows drop through summer. Hard details are scarce online beyond that, so treat it as a locals' spot: check current flows and ask around before heading out.
