Lucky 7 is a standing wave that forms if the furthest-from-I-70 roller on the Cameo Dam is open. It used to be the 7th roller, but since the first was turned into a fish ladder it now looks like it’s the 6th. The wave needs the furthest-away roller, Lucky 7, to be up, and it works best when the other rollers are down. When things line up — usually it happens in the early spring or late fall — the feature forms a nice surf wave. SUPers may have an easier time with it, since pop-up surfers may have some tough paddling out of the eddy to catch it, but it’s worth a shot. The feature can vary a lot depending on flow and what other gates are open, and it’s a rare enough event that it’s tough to calibrate what to expect, but it could be anything from a friendly six-inch green faced-wave to an angry five-foot surging wave/hole. It’s rare for Lucky 7 to be open during particularly high flows, but if it is be cautious — too much water in the channel would probably create a drowning machine. Also, since it’s usually only open in the winter shoulder seasons, pack warm gear.
The Colorado near Cameo gives the gauge information here, but the bigger question is whether the 7th (looks like the 6th now, since the first was converted to a fish latter) is open. Note that the feature will change drastically depending on flows and what other gates are open, from a 7″ friendly green shelf to a monster sticky wave-hole you don’t want a part of.

Access here is a little tricky. Park roadside along I-70, just above the Cameo Dam, and check out whether the roller is up. If it is, access it from the base (don’t drop in from above).
