Earthen bottom ponds have several
advantages. They are relatively simple to build, inexpensive
per unit of surface area, and if well constructed, of low maintenance
and usually long lasting. However, there are many drawbacks
to these ponds that make them a less advisable choice. Earthen
bottom ponds require a great deal of land as small earthen ponds
do not maintain themselves well. Small natural ponds never clear
properly due to the slow but invariable dissolution of soil
into the water and the difficulty of underwater shelf construction
with clay soils. In addition, any of the natural occurrences
such as moles and insects digging into the pond will have a
greater effect on smaller ponds. Most plants in earthen ponds
are planted directly into the soil, as plant roots often creep
over the edge of pots and escape. Once out of the pot, most
aquatic plants become very aggressive with their spread being
checked only by water depth. For these reasons, earthen bottom
ponds, especially small ones, are not recommended.
If the decision is made to
build an earthen pond, the soil must have a relatively high clay
content which makes the soil more difficult to work. Due to the
required size and land needed, they are more expensive per pond.
Plants in them are prone to grow more vegetatively and flower
less. Plants, fish, and other wildlife are harder to maintain.
Unwanted guests to the pond will be more common and much harder
to control. The water may often be muddy in appearance. If fish
are included in the pond, they will keep the water muddied as
they forage on the bottom.
The basic construction of earthen bottom ponds
starts with size and shape designs. Once these factors are determined,
remove the soil plus 6 inches for relining. Bring back onto the
site enough of the heaviest (highest clay content) soil that you
have and line the bottom and sides with a 6 inch layer. This soil
must be wetted as it is returned and rolled until all of the structure
is broken down and the soil becomes slick. This is called "puddling"
the soil and creates a layer almost impervious to water. Then
wait for enough rain to fill the pond before planting.
