These Lakes, Ponds, and Reservoirs have been broken down by counties and listed from north to south.  We have started with the four western counties of Massachusetts and intend to work our way east over time.  Keep visiting for new information.  For the most part, I have eliminated lake paddles that are small except for the popular ones (i.e Bennedict Pond in Berkshire County or Puffers Pond in Hampshire County).  If you feel there is some significant paddles missing, please recommend it!  If you have information that would be useful, I will add it.  When I have time I will investigate to add it to the list.

Confusing Definitions
Massachusetts Great Ponds

           Any project located in, on, over or under the water of a great pond is within the jurisdiction of Chapter 91. A great pond is defined as any pond or lake that contained more than 10 acres in its natural state. Ponds that once measured 10 or more acres in their natural state, but which are now smaller, are still considered great ponds.

Chapter 91
         Chapter 91 of the Massachusetts General Laws is the chief vehicle for regulating development activities in and around great ponds, rivers and the ocean.  Chapter 91 is based on the public trust doctrine, by which the Commonwealth holds these water bodies in trust for the benefit of the public.  Section 9.2 defines Great Ponds as waterbodies that are over 10 acres in their natural state, as calculated based on the surface area of lands lying below the natural high water mark.  This includes water bodies that have been artificially enhanced by dams or other methods.  The title to such lands is held by the Commonwealth, in trust to the public, subject to any rights which the applicant demonstrates have been granted by the Commonwealth.  Department of Environmental Protection shall assume that any pond presently larger then ten acres is a Great Pond unless the applicant presents topographic, historic or other information demonstrating that the original size of the pond was less than ten acres, prior to any alteration by damming or other human activity.
