Shade Reduces Algae

Algae Shade 1.jpg

Lakes with no shade produces more algae


Algae thrive on sunlight, particularly in the warm, shallow water near the shore. Any way we reduce sunlight reduces algae. Some of the most common species of algae start growing in shallow water on the lake bottom. When the alga matures, it floats to the surface. If we shade the bottom, we stop the algae.

Aquatic plants growing along the shore provide shade. A well-planted shoreline stops both algae & erosion.

Water lilies are an excellent plant to block sunlight.

Their wide leaves act as an aquatic forest canopy leaving open, shady areas under the surface. Since lilies grow in shallow water, they provide shade where it’s needed most.


Pond Dye: Sunscreen for your Lake

Pond dye is a vegetable oil product that blocks ultraviolet sunrays. It contains no toxic chemicals that harm aquatic wildlife. The only drawback to pond dye is that heavy rains wash it out of the lake. Ask Beautiful Ponds if this is a good choice for your lake. 

Trees are another source of shade. You may remember natural lakes you have visited. Most lakes throughout the continent are surrounded by mature trees. These trees provide a home for many wildlife species, but also give valuable shade to the water.

Shade also reduces water temperature & slows algae growth. This tree is 15 feet from the lake & provides cooler, shady water.
