"[1] The town of Minden, about 30 kilometres (19 mi) north, was named Gull River prior to April 1, 1859.

[2] The Gull River begins at Longboot Lake in the geographic township of Bruton in Dysart et al, Haliburton County.

[4] While the original purpose of this was to aid lumberjacks — who were cutting pine, spruce and hemlock in the area — in sending logs downstream to Trenton after the initial spring flooding had subsided, it would serve a dual purpose when the lock between Balsam Lake and Cameron Lake was completed in 1873, connecting Trenton with Coboconk.

Lake levels generally swell during the spring thaw and late fall, and settle back to normal by mid-June.

[5] Most of the lake front property on the lower sections of the Gull River system was divided into deep narrow lots in the 1830s,[6] unlike the regular-sized concessions in the adjacent land.
