Seems like everyone already has their questions answered but some more FYI. The wave is called Lucky 7, because it is kind of hard to find, harder to find running, and is the seventh gate over from I-70. When the gates are open at lower flows it is a 3 foot high wave hole awesome for ends, blunts, loops, and whatever else. Sticky in the middle and easy to flush on the sides. A little shallow so bring your spud boat and paddle like hell to get on to the wave. At higher low flows it turns into a big wave, wide enough for two boaters to be doing blunts, spins, and other wave moves, but mush harder to get on so bring a faster boat, like an Id.
The wave is about half a mile below Big Sur. Pull over in a dirt turnout on I-70 west directly next to the dam. Then hike down below the dam and paddle to the other side of the river. DO NOT get out on the opposite side of the river on the dam structure. The construction workers are cool with it, but the dam employees and canal guys are not.
It's a little bit of a drive for just Lucky 7, but is great to combine with a one day Westwater trip for a freestyle weekend. If the snow starts to suck then I would like to make a weekend of it if anyone is interested.
Props to the Mesa paddlers that I met at Gore. It is good to see that someone is putting the wave to good use now that Travis Winn and myself have moved from Junction.
ps The duct tape is primarily used to tape your hands to your paddle since it is too cold to hold on to it otherwise...
