What is the primary goal of retention ponds concerning aquatic ecosystems?

The primary goal of retention ponds in relation to aquatic ecosystems is to manage nutrient loads before they reach larger bodies of water. These ponds are designed to capture stormwater runoff, which often contains various pollutants and excess nutrients, such as nitrogen and phosphorus, that can lead to harmful algal blooms and degradation of water quality in streams, rivers, and lakes. By detaining and treating this runoff, retention ponds act as a filtration system, allowing for sedimentation and biological uptake of nutrients, thus protecting downstream aquatic environments. This function is vital in maintaining the health of aquatic ecosystems, safeguarding the balance of these ecosystems and promoting biodiversity.

While aesthetic appeal, renewable energy generation, and recreational opportunities are secondary benefits related to retention ponds, they are not the primary purpose. The focus on nutrient management is essential for environmental protection and sustainability.
