Course
The river arises in two branches, one east, the other west. The East Branch begins just north of East Haven. It flows southwest through Hartwellville in East Haven, then into East Burke.
The West Branch starts as several small forks near Crystal Lake, northeast of Sutton. The Montreal, Maine and Atlantic Railway lines follows the West Branch of the Passumpsic until it converges with the East Branch in Lyndonville.
From Lyndonville, the river proceeds southerly through St. Johnsbury Center, St. Johnsbury, Passumpsic, and Barnet, and into the Connecticut River near Nine Island.
