Leadmine Pond

Last Updated: 3/2018
       Largemouth bass provide fair fishing; large yellow perch and white perch provide productive panfishing. 

      Leadmine is an average size two story pond located in Sturbridge about one mile west of Route 84 near the Holland town line. The shoreline is 90% developed with summer homes. Aquatic weeds are scant with some patches of lily pads. Large boulders are numerous along the shoreline.
       The state visits the pond every year and does sampling.  A recorded  bottom temperature of 34 degrees was recorded in 2016.  
Fresh water has it's greatest density at 4 degrees C (39.2 F).  As the temperature of warm water decreases, the water molecules slow down and the density increases.  At 4 °C, the clusters start forming.  The molecules are still slowing down and coming closer together, but the formation of clusters makes the molecules be further apart.  Cluster formation is the bigger effect, so the density starts to decrease. Thus, the density of water is a maximum at 4 °C. As the water continues to cool the molecules begin to form a crystaline structure.  There is more empty space between molecules and therefore less dense.  This is why ice floats on water.

        The island in the south is worth a stop.  Take a quiet walk and stretch your legs.

Tantiusques (Graphite Mine)​
Trustees of Reservation

        Tantiusques (“tan-te-us-quays”) – a Nipmuc word meaning “to a black deposit between two hills” – was the center of one of New England's first mining operations.
       A short loop trail (1.5 miles) leads through quiet woods; a spur trail passes through the Leadmine Wildlife Management Area and ends at the Robert Crowd Site. Visitors can view the foundations of the house and barn of the African-American and Native American man who worked at the mine in the 1850s.
       The Nipmuc originally mined here for graphite to make ceremonial paints. In 1644, John Winthrop, Jr., son of the first governor of the Massachusetts Bay Colony, purchased the mine with hopes of extracting lead and iron. In the early 19th century, Captain Joseph Dixon and his son worked here before founding the J. D. Crucible Company of New Jersey, famous manufacturers of pencils.
      Today, careful observers can see the mine cuts, ditches, and tailings piles made by the various mining operations. The mineshaft that tunnels into the face of the low ridge is the most recent of all the excavations, dating to 1902. Most of the mining at Tantiusques was of the open trench variety. The cut along the top of the ridge is the partially filled-in remainder of what was once a several thousand foot-long trench, 20 to 50 feet in depth and roughly 6 feet in width, which followed the vein of graphite
