Pondering pond problems

Ponds are nearly as popular as fescue pastures on Tennessee farms. As a source of recreation, water for livestock and wildlife, an erosion control measure, or simply an addition to the scenic beauty of the rural landscape, a pond is an asset to landowners.

A picturesque, well-built pond, however, takes careful planning and annual maintenance to keep it looking its best and serving its purposes most effectively.

Here are a few pond management tips:

• Check your pond at least monthly for the presence of algae and pond plants, especially in mid to late summer. That's also a good time to remove any woody vegetation from the pond's dike.
• There are no “quick fixes” for severe weed and algae problems, but herbicides like Reward, Rodeo, and Navigate are recommended for broadleaf weed control while Cutrine Plus, Copper Sulphate, and Aquashade will prevent and control most kinds of blue and green algae. Pond owners should follow label directions carefully as some of these products can be toxic to fish.
• Grass carp are a natural method of weed control, but they, too, require time to take care of problems. It's best to put the grass carp in, let the weeds die out this winter, and let the carp have a fresh start next spring.
• Water clarity has a significant impact on weed problems. Most pond owners strive to keep the water as clear as possible, which actually promotes the growth of aquatic plants. If a bright object can be seen on the bottom of the pond at a depth of 18 inches or more, the pond needs to be fertilized.
• The Extension Service recommends fertilizing with 100 pounds of an 8-8-2 blend or 40 pounds of 20-20-5 per application until proper color develops in the water. Liquid fertilizers like 10-34-0 and 13-38-0 can also be used. Begin in early spring with two applications, two weeks apart, and then follow up with one application per month through October.
• Landowners considering the addition of a pond should carefully consider its design and seek advice from professionals like those at their local NRCS or Extension office before beginning construction.
