Contact: Jason Smith 517-290-4601

The Department of Environment, Great Lakes, and Energy (EGLE), in partnership with the United States Environmental Protection Agency (EPA) would like to announce the release of How's My Waterway.  How's My Waterway replaces Michigan's Surface Water Information Management (MiSWIM) System, opening access to more current statewide, as well as nationwide, water quality monitoring data.

Enter How's My Waterway

Users of How's My Waterway will have access to nationwide water quality monitoring data, as well as up to date 305(b) and 303(d) designated use support information.  Search on the Community, State, or National level to see data corresponding to fish consumption, swimming/recreation, as well as drinking water.

Any questions regarding this new system can be addressed using the Help functions in How's My Waterway, or you can contact Jason Smith, EGLE, at 517-290-4601 or email at
