Ponds are known more for largemouth bass than smallmouth bass, but there are some ponds out there that have some good smallmouth bass fishing.  Smallmouth bass prefer deeper, colder water than largemouth bass, so smallmouth bass don’t usually do as well in ponds once water temperatures warm up in the summer time.  Some ponds in the northern part of the U.S. have some good smallmouth bass fishing because of the colder water temperatures, but don’t expect to find that many ponds out there that have good smallmouth bass fishing.  Aerators and moving water can help create more oxygen in the water which can help smallmouth bass do better in ponds, so there may be some excellent private ponds that have some awesome smallmouth bass fishing.  For the most part though, you are better off searching for good smallmouth bass lakes in your area than ponds.
