When building a fish pond in your lansdscape, it is important to ensure that the sides of the pond are level. This allows it to fill properly and prevents possible overflows that will leave the water level too low. Insufficient water is not only unattractive, it can interfere with the maintenance of the pond and reduce the living space for your fish. The process of leveling a pond is relatively simple and can save a lot of trouble, if done at the right time in the construction process.
Leveling a Fish Pond
Place the 2x4 board across the width of the hole at one end of the pond, immediately after the hole has been excavated, but before any type of liner is put in place.
Place the carpenter's level on the 2x4 board at the mid-point between the sides of the fish pond. Take the level of the board.
Add soil the low side or remove soil from the high side of the hole until the level reads true. Ensure that the soil is tamped down well to prevent settling later.
Move the 2x4 board over one foot. Repeat the procedure, adding or removing soil until the board is level. Continue to level the pond in one foot increments until the entire length of the hole has been covered.
Turn the board 90 degrees and start the process again, along the width of the hole. Work your way across the hole, leveling as you go.
Ensure that there is sufficient soil around the pond hole to support the leveling work being done. This will help prevent later settling and failure of the soil when the pressure of the water in the pond bears against it.
