About Fresh Pond

Fresh Pond Reservation, Cambridge’s largest public open space, was designed in 1897 by brothers John Charles Olmstead and Frederic Law Olmstead Jr.

Other famous Olmsted Brothers landscape architectural projects included the U.S. Capitol and White House Grounds, Acadia National Park, New York City's Central Park, and the entire park system in Boston.

In the mid 1800s, Fresh Pond was a privately-owned ice production facility. Boston's "Ice King", Frederic Tudor, shipped ice from Fresh Pond to Europe, China, and India. Since 1852, Fresh Pond has been part of Cambridge’s water system.

Now, Fresh Pond is 155 acres of pond, and 162 acres of land, with a 2.25 mile (3.6 km) perimeter road and a golf course.

Fresh Pond Reservoir

Water comes to Fresh Pond via aqueduct from the Cambridge reservoir in Weston, and is purified at the Walter J. Sullivan Water Purification Facility adjacent to the Pond, on Fresh Pond Parkway. From there is pumped up to Payson Park Reservoir in Belmont, where gravity flows it back to Cambridge as drinking water.

Parking for this event will be very limited. Free shuttle buses will be running from City youth and senior centers, the Alewife T-stop and Cambridgeside Galleria.

This event is free and open to the public. For more information, call 617-349-4339.

Migratory Bird Walk #1

Bring insect repellent and binoculars if you have them. We will provide (Cambridge) water and apples. Limit 20 people. Bus leaves the Water Department lot promptly at 6:10. Registration is required.
