When you have an understanding of the conditions needed for the foundation, you should dig a test hole to determine the soil’s ability to house a pond. Ideally, your stocking my pond should be as deep as you plan to make your pond. The most suitable amount of groundwater in the test hole should be two to three feet from the bottom. If the water seems to be shady due to the muck soil composition, you might want to consider a shallow pond that will sit above the muck ground.
The best water for your dust should come from a well or larger water source. If you use a well, create a rocky run for your water to run over before it reaches the stocking my pond to create turbulence, aeration of water and allow other gases to be released. If you choose to connect your pond to a larger body of water, use a small stream to allow flow into the pond and make a stream of water to drain into either the same body of water or another. This helps keep the water from becoming stationary and maintains appropriate acid levels.
You should wait from a couple of months to a year before you make your stocking my pond. This will provide plenty of time for sediment to dissolve and create clean water. Water plants will also begin to grow and stabilize. Spring is the best time to fill the pond with fish so that their first couple of months in their new environment is not a stressful situation caused by severe cold. Store your pond with disease-free fish and research your state recommendations for the most suitable fish based on weather conditions.
