The Dead Diamond River is formed in the township of Atkinson and Gilmanton Academy Grant, New Hampshire by the juncture of the West Branch and the East Branch. The Dead Diamond heads south through logging country, and the Little Dead Diamond River joins from the west at Hell Gate, a set of rapids, just before the Dead Diamond enters the Dartmouth College Grant. The river traverses the length of the college grant before reaching the Magalloway River near the Maine border. The Swift Diamond River is a significant tributary which joins the Dead Diamond shortly upstream of the Magalloway.
