The SCDNR did stock quite a few trout this weekend in the Upstate, but the heat is going to be killer this weekend. If you normally catch and release, especially the wild trout, this would be a better weekend to either go ahead and keep them or don’t fish at all. They probably won’t make it with highs over 100 degrees and very low water levels.
If you do go out, drink plenty of the appropriate fluids, and monitor yourself and anyone else with you. 6x and 7x tippets will likely be the best, and I’d consider fishing subsurface flies in deeper cooler water for stocked and wild trout if you so choose.
