[WAR-rehn] is a town in Knox County, settled in 1736 and incorporated on November 7, 1776 from a portion of St. Georges Plantation.

Warren original area has been reduced by ceding land to Thomaston (1777, 1798, 1864), Cushing (1807), and Camden (1836).

Sign: Payson Park (2003)The Powder Mill Locks date from 1793 and supported a canal system allowing water transportation inland up the St. George River.

Today that system has virtually disappeared, though one can understand the need for it, considering that the river is impassible at certain points without it. A portion is visible at Payson Park on Route 90.

Adjacent to Thomaston, long a synonym for “State Prison,” Warren is now the site of the new state prison for Maine.

During the decade that  included the move of the prison, Warren gained about 1,000 “residents” in the U.S. Census while Thomaston lost a similar amount!

Georges River Canal

[Upper Falls, St. George River in Warren to Union town line, extending to Quantabacook Pond in Searsmont] Canals on Georges River, used for access to the forest in its watershed, were important for the development river valley.  Mills were built at its lower falls. Charles Barrett of Hope secured a charter from the Massachusetts General Court in 1793 to build locks and bridges creating a canal. Major General Henry Knox, who retired as Secretary of War in 1794, purchased the locks from Barrett and redeveloped mills at Upper Falls. By the late 1790s, boats ran through the river and Seven Tree Pond to Union. At Knox’s death in 1806, the canal was abandoned. Without maintenance, a few years of decay and freshets destroyed the locks.

The new Georges River Canal was opened in the spring of 1847 with traffic between Quantabacook Pond above Searsmont and tidewater at the Lower Falls in Warren. The Canal used no horses or mules on a towpath. Boats were poled by men in shallow water, and provided with sails when crossing the ponds. Maintenance costs for the wooden locks and for repairing washouts by the turbulent river were expensive. With increasing financial and maintenance problems, the canal closed in 1850.* [See photos above.]
