I just started getting into small mouth fishing around Columbia at the beginning of this summer. Ive been able to catch some in a few areas mostly on the Congaree. First spot is the river walk right under the West Columbia side of the Gervais st bridge. Plenty of bank access to wade in on the rocks or walk the bank. Next spot is Granby Park behind Carolinas baseball stadium. Some bank access but had most success walking out on the rocks. I have caught one nice smallmouth down behind the Zoo on the lower saluda while I was fishing for striper a few weeks ago
