Planning Your Pond
Creating a pond that holds water effectively involves careful planning and consideration of various factors.
Paying attention to the location, soil composition, and design will ensure your backyard pond retains water and functions well.
Determining Location
The location of your pond is critical. Choose a spot that gets adequate sunlight but also has some shade.
Too much sun can increase water evaporation, while a mix of sun and shade helps maintain the pond’s temperature and reduces algae growth.
Avoid placing the pond under large trees because fallen leaves can complicate maintenance.
Also, ensure that the site is easily accessible for any future maintenance and close to a water source for easy filling.
Evaluating Soil Composition
Soil composition is crucial for water retention. The ideal soil should contain at least 20% clay to hold water effectively.
If the soil is too sandy, water will easily seep through, causing leaks.
Test the soil in your chosen location.
Commercial labs can measure the percentages of sand, silt, and clay in your soil to help you decide if additional clay or a liner is necessary.
Bentonite clay can be added to improve soil water retention if needed.
Designing for Water Retention
Designing your pond with water retention in mind involves several steps.
Use a gradual slope for the pond sides to prevent erosion and add stability.
Compacted sides and bottoms are essential; compact the soil thoroughly during the digging process.
Consider installing a pond liner made of rubber or plastic to prevent leaks, especially if natural soil conditions are inadequate.
Adding layers of Bentonite clay between soil layers can also significantly improve water retention.
