Why is Lake Erie a dead zone?
Dead Zones This stratification of lake water is due to the different densities of water with temperature change. The bacterial activity increases as dead algae and other materials settle to the bottom of the lake. Since the hypolimnion is much smaller than the upper layers, the oxygen can be depleted during the summer.
