The newly renovated pond in our North courtyard is similar to the previous pond, but one key difference is method of filtration.
The new pond utilizes a constructed wetland bog located on the upper tier that acts as the sole filter for the pond. This is the area where gravel is visible and only covered with very shallow water. As temperatures continue to rise, various aquatic plants will begin to grow in this area. The plants play a key role in water quality as they filter out sediments, reduce nutrients, and digest pathogens. Once the pond is biologically balanced it will sustain plant and animal life and maintain water quality just as “mother nature” does, this eliminates the need to feed the Koi fish located within the pond.
The pond holds roughly 30,000 gallons of water. Water level will naturally fluctuate with the seasons and weather, but the pond contains automatic fill and overflow features which keep the water level within proper range. The pond circulates water from the lower pond, pumps it through the bog and into the upper pond at a rate of about 20,000 gallons per hour. That’s how much water comes over the water falls. Both upper and lower ponds contain the proper amount of Koi fish to be supported by the ecosystem and not over bare it. Additional wildlife such as the ducks are already enjoying the completion of the pond. Our maintenance and grounds team perform the maintenance that is required to keep the pond up and running throughout the seasons and biologically balanced as needed.
The renovated pond will be a beautiful feature to enjoy through all seasons. Keep your eye out for blooming iris and water lilies, there may even be a frog or turtle or two.
