Planning for a Pond

Points to Ponder

Pond type

The pond’s type and purpose may determine location—smaller fish ponds can be situated close to a terrace or patio for easy observation and relaxed enjoyment.  Larger ponds can be situated further away from the home and patio, and can also provide for wildlife viewing. Fountains and architectural ponds can be integrated into any garden design, enhancing its impact and serving as a focal point.

Sunlight exposure

Sunlight exposure may also impact ideal location. Four to six hours of direct sunlight daily is recommended for optimal pond health. Extended deep water zones help prevent water warming and algae formation in areas exposed to excessive sunlight.

Trees and shrubbery

Design your pondscape to include a variety of native trees and plants for visual interest. Situate trees with strong and penetrative root systems further from the perimeter to prevent root systems from interfering with pond’s structure. If trees with invasive root systems must be planted close to the pond, opt for a root barrier.  

Minimum Water Depth

To prevent freezing during winter, OASE recommends a minimum water depth of 31.5 inches. Ponds designed with liners—rather than pre-formed—provide a plethora of shape and size options. To prevent roots and small stones from damaging the liner, utilize an underlayment between the liner and dirt. For optimal results, insert the pond liner on a warm, sunny day.

Power and water connections

Building your pond close to a power source and water connections will streamline operation and control.

Tubing diameter

To avoid excessive friction loss, select tubing with the largest diameter possible.

Pond technology

The pump—a pond’s workhorse—should be carefully chosen and strategically placed. Filter pumps should be placed as deep as possible to remove pond floor sediment. Fountain pumps should be positioned close to the surface for convenient maintenance. Selecting the proper combination of pump, filter and UV Clarifier is critical to pond health.
