Michigan Flood Flow and Lowflow Discharge Databases

  • Flood Flow Discharge Database
    This database contains flood discharge estimates for various locations in Michigan. These estimates are used to design structures such as dams, bridges, and culverts. These estimates are also used to determine the extent of floodplain boundaries.
     

  • Low Flow Discharge Database
    Low flows are estimated for various points around the State and recorded here.  These values represent drought type conditions and are used in calculating worst case scenarios for the mixing of discharge waters into natural streams or rivers.
