Cochituate Aqueduct

In 1848 Lake Cochituate's water first flowed into Frog Pond on Boston Common in a ceremony that drew 100,000 people.

It eventually turns southeasterly, skirting around the east side of Morses Pond in Wellesley shortly after passing under Massachusetts Route 9.

It passes under Walnut and Cedar Streets in eastern Wellesley before descending to cross the Charles River into Newton on a stone bridge.

The aqueduct crossing of the river is via an iron siphon tube, whose original control houses on both sides have been demolished.

It then loops northward around Prospect Hill before turning southeast, passing through the Boston College campus, where its route has been obliterated by St. Thomas More Road.
