in contrast a newly created, deep, spring fed pond may have little life of any kind in it because of low temperatures and lack of food supply. all ponds age. a pond begins with mostly water, few nutrients, and little aquatic life. over time the pond accumulates nutrients. this enrichment process is called eutrophication. the addition of nutrients stimulates the growth of aquatic life. waterfall backgrounds. these organisms live and grow and die. their remains decay in the pond and the nutrients it took to grow them are released back into the water of the pond to keep the cycle going. eventually, though, there will be an accumulation of material that resists decay and the pond will fill up. it will become a bog and someday will resemble dry land. the process of return to dry land can happen in a decade or may take centuries.
as a pond owner your job is to slow the process down as much as possible. some of the principles you can employ are described below. maintaining vegetation in all areas through which water must flow to reach the pond is very beneficial to the pond. such buffers both slow water down and filter it. slow moving water allows sediment to drop out of the water. waterfall backgrounds. much phosphorus is attached to soil particles so that sedimentation is effective in keeping phosphorus out of the pond. keeping sediment out of the pond also prevents the pond from being made shallow by filling it with sediment. this contributes directly to our primary objective keeping the pond from returning to dry land. a deeper pond, will also be a cooler pond. a general principle of biology is that lower temperatures slow the growth of organisms. so again the buffer area contributes to conditions that help slow the aging process for the pond. ponds are most satisfactory when there is a complete and balanced food web in place. starting at the top this means that planktonic algae are present in sufficient quantity to feed some zooplankton. waterfall backgrounds. the zooplankton in turn provides food for the smallest fish and aquatic insects. these in turn become prey for larger fish which finally may be taken by raccoons, bears, or fishermen.
