What I heard was they went into the restricted area and fell in. The BRA was releasing water with one floater, so there was some current. People always take risks every year fishing below that dam. I've done it before and it can end poorly. I've fished below PK, Bull Shoals, Beaver, Keystone, Eufaula, fort Gobson and Texoma. You can catch a lot of fish at times but you can die easily if the current gets you.
Don't fish when it's doing this
I've watched people put Kayaks in when the flow was so great lead would not sink
