1. As a general rule trees are not planted on or near earth dams because their roots can penetrate the waterproof clay core and cause leaks or dam failure.
2. If dam does NOT have a clay core or if erosion is a problem then planting trees on dams is a good idea. Tree roots bind soil together much like steel mesh and reinforcing bars = "rebar". The best trees for this purpose have extensive root systems. Willow is a good example. Bamboo is a grass plant often used to reinforce dikes and dams because it has a tough network of surface roots highly resistant to water erosion. Bamboo acts like "geotextile". 1 acre of bamboo has more than 40 MILES of primary roots.
3. Be careful and set traps for muskrats if any set up residence in your dam. Muskrat burrows can seriously weaken earth dams = high chance of dam failure.
4. Clearing out unnecessary trees will let more light into your pond = more phytoplankton = more fish food. Well managed fish ponds should be "pea soup" green. The standard test is to stick your arm into the pond until water reaches your elbow; if you can see your hand pond does not have
enough nutrients. If you cannot see your hand pond has enough fertilizer. Grow ducks on your pond and they will fertilize the water for you. Use trash fish = bluegills and sunfish to fertilize garden crops.
5. Pond weeds and algae make excellent mulch and fertilizer. Plant your garden near your pond so you don't have to haul weeds any great distance. If you plant your garden down slope from your pond you can set up a gravity irrigation system. At minimum, all you need is a garden hose to set up a simple siphon.
6. Dutch White Clover =
Trifolium repens is often planted on earth dams because it has an extensive surface root system but only grows 6 to 8 inches high. Any low-growing ground cover makes dam maintenance easier = less mowing.
7. Consider installing a
solar powered pond aerator to keep down mosquitoes and improve water quality for pond fish. A pond aerator will greatly increase fish survival over winter.
