Learn About Inland Lakes and Streams

Did you know? Michigan has over 52,000 miles of streams, and more than 10,899 inland lakes.

These precious water resources and the benefits they provide are protected by several state laws from impairment due to pollution, physical alterations and nuisance aquatic species. The state's water resources are monitored by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) and partnering organizations to determine the water quality, the quantity and quality of aquatic habitat, the health of aquatic communities, and compliance with state laws.

Aquatic Invasive Species

Different than aquatic nuisance, an invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan's economy, environment, or human health.

Aquatic Nuisance Control

Although aquatic plants are a natural component of every aquatic ecosystem, excessive plant growth can sometimes be a nuisance for riparian property owners and other lake users.

How is my water quality monitored?

Water resources in Michigan are everywhere, and monitoring the quality of these resources is vital to ensuring a high quality of life for future generations. Water quality monitoring is fundamental to understanding the environment around us and is an essential component of our mission.  Monitoring tells us the what, where, and when of environmental issues.  Without water quality monitoring, we wouldn’t know what pollutants are in a water body, where you can eat the fish, and when the beaches are safe for swimming.
