These native creatures are musical, fun to watch and relatively easy to attract. According to Jeff Jackson, University of Georgia extension wildlife specialist, it's easy to make a little pond for frogs. Just dig a shallow hole, line it with plastic, and fill it with water. There are special pond liners that will last for years. But if your bank account was drained by that last gas bill, you can always use heavy black builder's plastic.
Black plastic is cheap.
And if it develops a leak, you can always just install a new piece on top of the old one. A pond that is 10-20 inches deep will work well, and it doesn't have to be big. Even a small pond with only one or two square yards of surface area will attract frogs. Pond edges are important. They should taper gradually from shallow to deep so that frogs can easily crawl out.
