One of the absolute water garden favorites is awesome Koi ponds. With more and more people getting away from the maintenance issues of liner ponds with heavy rocks a preformed garden pond might just be the answer. Here at Everything Waterfalls we carry six backyard ponds with a depth of at least 24" and containing up to 60 gallons of water. Our medium size fish ponds will be able to house smaller type fish while our large ponds will make the Koi lovers happy. Our artificial rocks make excellent rock garden ponds and many of our beautiful waterfall designs will complement for the comple water garden oasis.
