Scioto

The runnable sections are river left below the damn. There are two channels. The furthest left channel has some boogie water then a stout undercut 4 ft ledge followed by a short pool ending in a manky 10 footer with rocks on the right. The next channel over is where the sweet goods are with a 4-5 ft boof into a channelized shoot followed by boogie water turning into a 20 ft slide ending with a meaty 10-12 footer. There is an underwater shelf and plenty of strainers so bring safety and make sure you know where to go. I have footage of this on youtube under East Fork Scioto Waterfall Descents.

I've been kayaking the O'Shaughnessy reservoir for about a year and I've never had any problems. The water is deep(over 6 feet) and calm, usually there are many kayaks and sails running along with no problems.
I am surprised about your comment, so I thought maybe you are misinformed.

There is no rapid here. Only a huge dam. The put-in and take-out points are wrong. Don't run it.

I live very close to here and I never knew there was a runnable rapid here. Is it only accessible during period of very high flow? Looks pretty crazy from the youtube video.

This section gets pretty cool for columbus at high water, just hit the second channel from the left
