The upper limit is a rough guess, based on historical data for this gauge. If you have better beta, please add a comment.
Easily run but a total boat abuser...has a gravelly textured surface and in all but the highest conditions you just sandpaper your way down. Get close to the edge, take a good look and either pick the deepest spot or decide you like your boat and portage right.
Lots of sharp rocks in the run out so not a place to get flipped but if you're in danger of getting flipped here this is good place to call it a day. Note that in the distant past like the early 2000's the rocks were blown out and there were nasty holes at the bottom...and we're probably 1 big storm from this happening again, so like any dam, use your discretion.
Since the dam is hell on boats if you're just running the gorge, parking on the southeast side of the bridge and access either right by the bridge on the west (dam) side or thru woods on east side.
