The portion of Devens land just north of Route 2 sits upon a major aquifer.
The Mirror Lakes (Mirror Lake and Little Mirror Lake) are a large kettle hole (a deep pond that formed when the last glaciers covering New England slowly melted away) where the underground aquifer is visible at the surface. The larger of the two lakes (Mirror Lake) is used, in season, as a recreation area for swimming and fishing.
In 2006, Mirror Lake Management (MLM) Inc. assumed responsibility for the operations of Mirror Lake’s waterfront. MLM is a sister corporation of Marcus Lewis Enterprises Inc.
Mirror Lake is zoned as conservation land and therefore is governed by regulations that are intended to protect and preserve its historic environment.
- Electric, powered motors for small watercraft are allowed while gas powered motors are not.
- All motor vehicles are prohibited from driving down the hill to the waterfront and must be parked at the upper parking lot.
- Charcoal grills and alcoholic beverages are prohibited.
- No dogs are allowed.
- Recreational flotation devices (noodles, inner tubes/rings, water wings, kick boards, and boogie boards) are not allowed.
- A number of small watercraft can be rented throughout the day including kayaks, canoes, rowboats and paddle boats.
