Eutrophication is when excessive nutrients build up in waterways such as rivers, lakes, and streams. This creates high amounts of nutrients for plants and algae. When algae blooms occur, they deplete oxygen and create dead zones. Lake Okeechobee contains a large amount of eutrified water. The proposed Reservoir would allow water collected in Lake Okeechobee to be filtered out so that those nutrients can benefit plants within wetlands or agriculture. This would reduce the amount of eutrified water being poured into estuaries which damages marine life and ecosystems.
