Just have to add this - catfish (channel, flat or blue) DON'T dig holes. There feets are shaped all wrong to hold a shovel.

Seriously, though, they may slosh around and clean out a depression, but they don't "dig" anymore than BG or LMB. Now, if there's an existing hole (muskrat den, or something) they may go in and waller around a bit and enlarge it somewhat, but they'll have absolutely no effect on your dam or banks.

Oh by the way...MAN that is a gorgeous pond/tank/lake/small reservoir...

I've swum in and handfished enough ponds to know this much, at least. :rolleyes:

In a lifetime, the average driver will honk 15,250 times. My wife figures I'm due to die any day now...
