Mm-hmm.

We know that some of the nutrients and sediments coming off an ag field are going to settle at the bottom and not make it all the way to Lake Erie.

So when are those being resuspended or moved, or are they? We don't know if they're just being trapped down there.

So we have studied that a little bit.

There's some great work coming out of the USGS.

OSU's got some work in that space.

Uh, University of Southern Illinois I think is the other one that does.

Yeah.
