Hundreds packed a theater in Watertown on Saturday to celebrate an event that took place 250 years before. The town was the site of the signing of the United States’ first treaty with a foreign nation — the Treaty of Watertown. Descendants of the signers of the document from the Mi’kmaq and Maliseet tribes emphasized that the agreement that was forged as a wartime alliance also created friendships and provided rights and protections for the signers that are still important in 2026. The City of Watertown joined with the Historical Society of Watertown, and members of Maliseet, Mi’kmaq tribes, as well as representatives of the Massachusett Tribe, whose territory includes Watertown, to plan a grand celebration of the 250th anniversary of the Treaty of Watertown on Saturday, July 18, 2026 at the Mosesian Center for the Arts. Around 50 members of the Mi’kmaq and Maliseet tribes came down from Maine, and parts of Canada for the Treaty celebration.

Water & Sewer Rates Increasing More Than Expected Due to Error in Calculations

Watertown residents will see an increase of 4.5% in both the water and sewer rates for the fiscal year that began on July 1, 2026, which is slightly higher than forecasted a year ago. However, the future increase could be significantly higher than projected due in part to an error made calculating future year revenues. Last year, the City’s consultants, Weston & Sampson, projected a 4% increase in water and sewer rates in FY 2027. The actual increase will be half a percent higher, said Department of Public Works Director Thomas Brady. With the 4.5% increase, residents using 1,800 cubic feet of water will increase $5.10 per quarter ($115.28 to $120.38), and the sewer bill for using 1,800 cubic feet will increase $9.54 per quarter, from $213.48 to $223.02.
