These are all of the water sources directly on the towpath. Note most are hand pumps of treated well water, with only a few “city water” taps. Almost all are unavailable from mid-November until the spring. Check the NPS website for the status of any of these ahead of your trip.

Note, the closing and phased-reopening of the water sources due to COVID-19 means some of these are going to be unavailable at times for the near future. Carry more water and consider carrying a water filter with you.  Always check the NPS conditions page for a current list of what is open and what is closed.
