Pond Maintenance

Constructing a pond is a significant investment, but if managed properly, it can yield many benefits. On this page, find information on pond maintenance and construction. Topics covered include pond construction, best management practices, water quality concerns, and pond permits.

Pond Construction

Building a new pond often requires permission from various government agencies. In Pennsylvania, the water quality and quantity regulations are overseen by the Department of Environmental Protection (DEP). During pond construction, a DEP permit may be needed if using a surface stream as a water source or if the pond is especially large.

Before constructing a pond, it is also good advice to consult with the local Natural Resources Conservation Services (NRCS) office. The NRCS offers assistance to landowners on conserving soil and water resources. In addition, they can provide technical assistance, as well as information on whether a permit is required.

Farm pond safety is a concern for many pond owners. Practices to consider when designing and constructing ponds include fencing, exercising caution when opening septic tanks, and inserting rescue posts (near ponds used for swimming). Penn State Extension’s resources are available for additional information, including advice on basic pond measurements and management.

Pond Maintenance

Careful pond maintenance is essential for keeping the ecosystem healthy. Prevalent pond issues that affect the pond’s health include excessive plant and algae growth, nuisance wildlife, and water quality problems.

Pond maintenance practices to consider include testing the water quality, utilizing nutrient control methods such as riparian buffers, and inspecting the pond’s current conditions.

Regular assessment and inspection of the pond are crucial for identifying problems early on and preventing serious harm to the pond’s health. Common components of pond inspection that should be examined include watershed, water sources, dams, banks, and overflow pipes. Additionally, the pond water level should be routinely monitored for early signs of leakage.

In this section, learn more about maintaining a pond and identifying potential issues. Join the Management for Rural and Farm Pond Owners online course to access tips on farm pond maintenance. The course provides further information on determining your pond’s goals, implementing safety practices, and managing wildlife in and around the pond.

Pond Fish and Aquatic Plants Management

Fish and aquatic plants are an invaluable part of many ponds. If you are looking to start a pond fishery, remember that proper management is necessary for maintaining a healthy ecosystem. Before getting started with fish pond construction, note that all species have specific water temperature tolerances. In order to successfully stock and manage pond fish, knowledge of typical water temperature conditions in the pond is important.

Regardless of the pond’s main purpose, aquatic plants and algae provide a number of benefits, such as serving as food and habitat for wildlife. The key to maintaining pond vegetation is to provide an optimum amount of plants while avoiding excessive growth of nuisance plants and algae.

If plants and algae do reach a nuisance level, it is advised to first explore options that can manage the plant with the least damage to the pond’s health. Physical removal of plants is ideal as it also removes the nutrients in the plant. In some cases, excessive vegetation may also be controlled by stocking grass carp.

If applying aquatic herbicides is recommended, it is vital that they are used adequately. Discover more about pond maintenance and aquatic herbicide application with Penn State Extension’s resources.
