As August's heat sets in, protecting your pond from low water levels will become more important than ever. High temperatures, excess sunlight and drought conditions can lead to rapid garden pond evaporation, fish stress and algae growth.
Check out our tips below to reduce garden pond evaporation and ensure your pond thrives throughout the summer months.
Fact: A standard pond can lose 1 to 3 inches of water per week as a result of evaporation in warm water (rates can vary).
1) How Plants can Support your Pond Ecosystem
Aquatic plants play a vital role in maintaining a healthy pond environment. Their shade helps lower water temperatures, which in turn increases oxygen levels - essential for fish and other aquatic life. Cooler shaded water also discourages algae growth, which tends to thrive in warm, sunlit conditions. Floating and marginal plants not only provide shade but also create shelter for fish, frogs and other pond inhabitants, helping to reduce stress and support a balanced ecosystem. Additionally, species like Water Lilies and Lotus enhance the pond's visual appeal, adding beauty and diversity to the landscape.
Tip: Try to cover 40-60% of your pond surface with floating plants in summer. This gives you a good balance between shade, oxygenation, and light for aquatic life.
2) Shading Plants to Prevent Water Evaporation
Direct sunlight is a major cause of pond water evaporation. Floating plants that cover the surface helps block much of this sunlight, reducing the heat that drives evaporation. With less sun exposure, the water remains cooler, and cooler water evaporates more slowly. Additionally, a shaded pond - especially one surrounded by vegetation - can create a slightly more humid microclimate. Higher humidity around the pond slows evaporation further, as the moist air can't absorb as much additional water vapor.
3) Best Plants for Shading a Pond
- Floating Plants: Water Lilies, Water Hyacinth, Duckweed
- Marginal Plants: Pickerelweed, Taro, Cattails
- Submerged Plants: Not for shade, but support oxygen levels
4) It could be a Liner Puncture
If you've noticed your pond water level dropping, one possible culprit could be a puncture in the liner. These leaks can cause either a sudden drop in water or a slow, steady loss over time. A good way to locate the issue is to observe where the water stops draining - this often indicates the puncture is above that level, right near the waterline.
