Watershed maps

FRWA was one of the first conservation organizations in Connecticut to utilize Geographic Information Systems (GIS) to represent natural resource information in map form. GIS is a key element of our efforts with towns to achieve better conservation planning through envisioning resources to protect, and is helpful in providing you with useful maps like those below created by FRWA’s GIS Manager, Jeff Bolton.

  • Farmington River Watershed Map (gray PDF, 3.5 MB)  Color (PDF, 4.4 MB):  There are 33 towns in the Farmington River Watershed covering 609 square miles of land. See where your town is located on the Farmington River Watershed map.
  • Farmington River Watershed Reservoir Map: This map shows the East, West and Main Branch of the 81 mile long Farmington River as well as the Nepaug Reservoir.   The location of each reservoir is described as well as its usage, ownership, capacity and age.
  • Farmington River Watershed Dams: Although data was not available on Massachusetts dams when we made this map, it is interesting to see how many smaller dams exist in the watershed. Think of this map as a journey into the River’s past when mills were a big part of local economies.
  • Upper Farmington River Potential Vernal Pools: Vernal pools are wetlands that are not wet year round and provide breeding habitats for critters like wood frogs, mole salamanders, and fairy shrimp. This is a GIS map of the potential vernal pools identified in a 5-town area of the Upper Farmington River Watershed as interpreted from aerial photos by a wetland scientist. This is not meant to represent actual vernal pools which must be identified on-the-ground and in-the-field.
  • Watershed Locator Map: Now that you know more about what is inside the Farmington River Watershed, you might be interested in how large the watershed appears superimposed on the states of Connecticut and Massachusetts.
