Watershed Map

Tips and Tricks for using MWCC’s Watershed Map

  • Watershed group boundaries may not include all the areas that are covered by a watershed group and instead follow the HUC (USGS hydrologic unit code) boundaries or counties that encompass the main stem of the major waterbody in each watershed. Likewise, boundaries represented here may also include multiple groups within a single HUC watershed.
  • To navigate watersheds with multiple groups (indicated by “1 of #” in the upper left of the information box), click the arrows in the upper right corner of the information box.
