It is indeed a fairly healthy fishery.
Unfortunately after some pretty good luck last year, so far this year I seem to keep landing down there on the wrong weekend.
I went down and spent two nights at Stumphole landing June 12th-14th. Never did find any large beds of Bream. I found some very nice males off the flats along the river back in Stumphole swamp, around the cypress trees, but can't say they were spawning. Don't know what the deal was. I fished all along the shoreline bordering the river. Probed out a little deeper hitting pockets of lily pads on the shallow flats and never found any beds nor hardly any Bream at all. Finally found a few along the trees just off those shallower flats, in about 3'-4' of water. Fishing any water over 4' deep produced nothing. I only kept about a dozen. Got run off the lake by thunderstorms rolling around 2:30-ish.

Sunday I drove down to Black River and caught a few Shellcrackers and plenty of Warmouth. Also tangled with a few Bowfin (Mudfish) on UL tackle which was fun. Again the Bream were elusive. I was surprised one of the Shellcrackers had eggs. (?)

Out back in Stumphole swamp early Monday and try as I might, I could only pick up a couple of decent size Bream. I had some luck picking up a decent one now and then on Saturday but no luck today. Like fishing in a desert. Ran into several other boats which were having similar luck. I told another boat when they asked me how I was doing, "A man that can't catch Bream at Santee deserves to go hungry!" They informed me they were having the same luck. Packed in around 2:00 when the temperature hit 90° and headed back to the NC mountains.

I did see the biggest gator I've ever seen in the wild. Heard what I think was one bellowing right at sunup too.
