Sunset Lake (Braintree, Massachusetts)

The Cochato River is a stream rising from Avon, Massachusetts and running several miles north to its confluence with the Monatiquot River in Braintree. It is part of the Weymouth Fore River watershed and empties into Boston Harbor. The river serves as the boundary between Braintree and Randolph. The river previously fed the Richardi Reservoir, a water system serving nearly 90,000 people in the Towns of Holbrook, Randolph, and Braintree. This use ended in the 1980s, however, due to severe pollution from the Baird & McGuire company. From 1912 to 1983, the Baird & McGuire chemical manufacturing facility was operated near the river in Holbrook, manufacturing products such as pesticides, disinfectants, soaps, and solvents. Between 1954 and 1977, the company was fined at least 35 times by various state and federal agencies for numerous violations. Because of their poor storage and disposal practices, industrial waste was discharged into the soil, river, wetlands, and a gravel pit. The facility was closed in 1983 and declared a "superfund" site. The Environmental Protection Agency dredged and treated over 4,000 cubic yards (3,100 m3) of sediments in the Cochato, with cleanup completed in 1997. The river has been monitored since that time.

The Gen. Sylvanus Thayer House, also known as the Sylvanus Thayer Birthplace, is an historic house at 786 Washington Street in Braintree, Massachusetts. It is operated by the Braintree Historical Society as the Thayer House Museum, which is open year-round. The 2+1⁄2-story wood-frame house was built in 1720 by Nathaniel Thayer and was subsequently expanded in the 1760s and again in the 19th century. General Sylvanus Thayer, known as the "father of West Point," was born in the house in 1785 and resided there until 1793. In 1958, the parcel of land on which the house sat was purchased by the Walworth Steel Company; rather than tearing the old house down, it was dismantled and moved approximately one mile down Washington Street to its present location. Roughly 60% of the timbers in the house are original, while the others have been replaced during restoration with materials appropriate to the late 18th century. The house is furnished to represent a middle-class agricultural household, like the Thayer family, in 1785–1793. The house was listed on the National Register of Historic Places in 1974. The Braintree Historical Society constructed a reproduction post-and-beam dairy barn to complement the Thayer House Museum in that same year. Both contain exhibit galleries and are open to the public. A cannon that was a gift from the U.S. Military at West Point, is on the front lawn of the House. Both wheels were reconstructed in by a wheel wright and a blacksmith, one for the wood and one for the iron tread, working together in Colonial Williamsburg, using only tools and techniques consistent with the period. The wheels were reinstalled and the cannon was rededicated in a formal Commemoration Ceremony on the front lawn of the Thayer House with the Williamsburg craftsmen present, on June 21, 2015.
