Lechmere Square is located at the intersection of Cambridge Street and First Street in East Cambridge, Massachusetts. It was originally named for the Colonial-era landowner Richard Lechmere, a Loyalist who returned to England at the beginning of the American Revolution. His lands were later seized by the new American government. The shoreline is shown as "Lechmere's Point" on Revolutionary War maps, and was the landing point for British troops en route to the Battles of Lexington and Concord.

The Assabet River is a small, 34.4-mile (55.4 km) long river located about 20 miles (30 km) west of Boston, Massachusetts, United States. The Assabet rises from a swampy area known as the Assabet Reservoir in Westborough, Massachusetts, and flows northeast before merging with the Sudbury River at Egg Rock in Concord, Massachusetts, to become the Concord River. The Organization for the Assabet, Sudbury and Concord Rivers, headquartered in West Concord, Massachusetts, is a non-profit organization dedicated to the preservation, protection, and enhancement of the natural and recreational features of these three rivers and their watershed. As the Concord River is a tributary of the Merrimack River, it and the Assabet and Sudbury rivers are part of the larger Merrimack River watershed.

In Falmouth, Route 28 turns north and continues through the western part of Plymouth County and the eastern part of Norfolk County; it then passes through downtown Boston before heading north via Lawrence to the New Hampshire state line, where it continues as New Hampshire Route 28.
East Cambridge is a neighborhood of Cambridge, Massachusetts. East Cambridge is bounded by the Charles River and the Charlestown neighborhood of Boston on the east, the Somerville border on the north, Broadway and Main Street on the south, and the railroad tracks on the west. Most of the streets form a grid aligned with Cambridge Street, which was laid out to directly connect what is now the Charles River Dam Bridge with what in 1809 was the heart of Cambridge, Harvard Square. The northern part of the grid is a roughly six by eight block residential area. Cambridge Street itself is retail commercial, along with Monsignor O'Brien Highway, the Twin Cities Plaza strip mall, and the enclosed Cambridgeside Galleria. Lechmere Square is the transportation hub for the northern side. The southern half of the grid is largely office and laboratory space for hundreds of dot-com companies, research labs and startups associated with MIT, biotechnology firms including Genzyme, Biogen and Moderna, the Athenaeum Press Building, light industry, an NRG Energy power station, and various small businesses. This half of the neighborhood is generally identified with Kendall Square. Along the waterfront are several hotels and taller apartment buildings.
The Malden River is a 2.3-mile-long (3.7 km) river in Malden, Medford, and Everett, Massachusetts. It is roughly 675 feet (206 m) wide at its widest point and is very narrow at its smallest point. Its banks are largely occupied by industrial business, and the river is scarcely used or even mentioned. Its water quality is worse than most local waters, including the Mystic River, into which it flows. The Mystic River Watershed Association is working and creating educational programs to help the environment. The Association works on projects to improve the Mystic River and tributaries, lakes and ponds and greenways along the waterfronts. Rivergreen Park is part of the Mystic Greenways and is along the Malden River. The Friends of the Malden River organize clean-up events.

The Merrimack Manufacturing Company was the first of the major textile mills constructed in Lowell. It was demolished around 1960.
The Holyoke Canal System is a system of power canals in Holyoke, Massachusetts. It is split into three canals based on elevation and distance from the inlet at the Holyoke Dam- the First Level Canal, Second Level Canal, and Third Level Canal. Constructed over a period between 1847 and 1892, the Canal System, along with the Dam, is recognized as a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers for its use in the development of the Venturi meter by Clemens Herschel, the first means of measuring large-scale flows, and the McCormick-Holyoke Turbine by John B. McCormick, which doubled the efficiency of turbines to more than 80% in its time.
