Access to the Low Flow Database is provided as a service to allow you to view discharges from previous requests for preliminary design purposes. The discharge values are only valid for the original requestor and for one year after the date they were issued. To obtain discharge information from the Hydrologic Studies Program, you may submit a request online. Go to michigan.gov/hydrology and click "Request a Flood Discharge or Low Flow Form" to access the current form. Note that you may be required to include the response to your discharge request with your permit application.
