I was on the meramec a couple years ago right at little Indian creek. I was casting my way back to the ramp. I heard and saw a huge mud surge coming down little Indian. It had rained south of me and I didn’t give it a thought until I saw it. I hightailed it down to the ramp and just got my boat out when it reached the ramp. Within a few minutes it was a raging muddy debris torrent. Crazy!
