Cycle to the Source Cambridge Watershed Bike Tour

Discover the Headwaters of the Cambridge Drinking Supply by Bike

Our 8th annual Cycle to the Source Watershed Tour on October 2, 2021 was a blast!

Check back in fall of 2022 for information about our 9th annual ride!



This annual event aims to connect CWD staff to the public, and encourages community members to consider where their water comes from. It is a fun, alternative way to share information about Cambridge water and past participants have greatly enjoyed the experience. Cycle to the Source encourages residents to:

  • See the watershed in a low-impact way.
  • Visit the reservoirs and gatehouses to further understand how water arrives at Fresh Pond
  • Meet the faces of the Cambridge Water Department watershed division
  • Get answers to questions regarding the supply, protection, transport, and treatment of Cambridge water before it reaches the tap
  • Understand the connections between land use and water quality in our watershed

A map of the tour route for 2021 can be found here.
