By Patio Pond, In The Back Garden, As A Collection Of Plants, Eugene, Oregon Ponds are small bodies of freshwater with shallow and still water, marsh, and aquatic plants. Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these.[from wikipedia]
