Trail Description

Look for the trailhead at the green Clark Bog sign in Hanover’s Forge Pond Park, near Parking Lot C. There is also access from King Street. Be sure to remain on marked trails (red blazes) and be mindful of Private Property signs. The Hanover Police Department’s Shooting Range is immediately adjacent! A metal gate marks the boundary between the Clark Bog Trail and the Old Rockland Fireworks Loop Trail.

Habitats and Wildlife

This property used to be a cranberry bog and a fireworks, so it features relatively wide, sandy paths around ponds and wetlands. Of particular interest is the extremely dense new growth of young trees where the cranberries used to grow.

It is part of the watershed of the Drinkwater River, which flows south through Forge and Factory Ponds. According to Martha Campbell’s Remembering Old Abington, the name “Drinkwater River” is said to be an Anglicized version of the original Native American name for the stream, Nannumackeuitt, “which meant that a hollow stem had to be used as a straw when sucking up water from this shallow, sluggish stream.” However in A Historical Sketch of the Town of Hanover, John S. Barry indicates that the name derives from the occasional of a new sawmill opening a short distance upstream of Forge Pond, near Ellis’s Bridge, after the original mill was burned down in 1676 during King Philips’ War. After “cold water, instead of spirituous liquors, was furnished as a beverage,” the term “Drinkwater” emerged.

The Indian Head River rises from the Drinkwater River and Factory Pond in West Hanover. It forms the boundary between Hanover and Hanson, and merges with Pembroke’s Herring Brook, a short distance downstream of Ludden’s Ford Park, to form the North River at a spot called The Crotch. The North River flows 12 miles through Pembroke, Hanover, Norwell, Marshfield and Scituate, eventually making its way to Massachusetts Bay and the Atlantic Ocean.
