In the 1990s many high tech manufacturing plants and expensive housing developments began to appear in the area around the lake.

This nutrient abundance and lack of circulation in the lower depths has caused severe algae problems.

The sun warms the top layer of lake water and makes it suitable for warm-water fish such as bass, bluegill and perch.

Algae clogs the surface of the lake to a depth of about 18 feet (5.5 m), so no oxygen from the air can penetrate to the deep, cold water at the bottom.

In Fall the Aquatic plants such as Elodea (elodia canadensis) and Algae die, they sink to the bottom, where they decay, using up still more oxygen, making the colder depths barren and lifeless.
