Getting Your Farm Pond Ready for Spring

As spring approaches, I’ve been receiving more calls from local pond owners looking for advice on preparing their farm ponds for the season. Managing a pond in the Florida Panhandle can be tricky—especially when dealing with spring-fed ponds. While these ponds are often beautifully clear, their constant water turnover makes management a challenge.

If you’re wondering how to get your pond ready for spring, here are some key considerations and resources to help guide you.

Start with a Water Quality Test

The first step in assessing your pond’s health is testing the water. I always recommend that pond owners bring a pint-sized water sample in a clean jar to their local Extension Office for analysis. Keep in mind that not all offices offer this service, and public testing options are limited. However, private labs and DIY testing kits are available—though they can be costly.

The most important parameters to check are pH, alkalinity, and hardness: pH should ideally range between 6 and 9 for a healthy fish population. Local ponds often hover around 6.5, making them slightly acidic.

Alkalinity and hardness measure the water’s ability to neutralize acids and buffer against sudden pH changes. For optimal pond health, alkalinity should be at least 20 mg/L, but many local ponds fall below this level.

Improving Pond Water Quality

If your pond’s water quality is less than ideal, there are two common ways to improve it: liming and fertilization.

Applying Agricultural Lime: Properly adding agricultural lime can raise alkalinity and stabilize pH levels. However, in high-flow ponds, lime tends to wash away quickly, making this method ineffective for ponds with constant discharge.

Fertilizing to Boost Productivity: Fertilization increases phytoplankton growth, which supports the pond’s entire food web, benefiting juvenile fish and invertebrates. Unfortunately, like lime, fertilizer is quickly washed out of high-flow ponds, making it ineffective in these cases.

Making the Best of Your Pond

If your pond has a continuous discharge due to spring flow, the best approach may be to embrace its natural clarity, even if it doesn’t support a thriving fish population. However, if your pond retains water without frequent outflow, you may be able to enhance its productivity with the right amendments.
