What is one reason to maintain less than 3 feet of depth in a pond?

Maintaining less than 3 feet of depth in a pond can help discourage excessive aquatic vegetation growth. Shallow waters tend to warm up more quickly, which can lead to increased sunlight penetration and foster the growth of certain aquatic plants. However, keeping the depth shallow can inhibit the establishment and dominance of some fast-growing species that thrive in deeper, cooler waters. By managing the depth, the overall nutrient levels can be kept lower, which can also help in controlling algal blooms and unwanted aquatic vegetation. This practice aids in creating a balanced ecosystem where desirable plant and animal life can thrive while keeping invasive or problematic species at bay.
