Songo Lock
This lock, originally built of stone masonry in 1830, was a vital link in the 50 mile long waterway from Portland Harbor to Harrison at the head of Long Lake until the advent of the railroad in 1869. At one time 100 “canal boats” were engaged in freighting lumber out and supplies in through the waterway. These boats were 65’ long and were towed by horses and oxen through the canal, sailed across the lakes, and poled up the Songo River. A total of 27 similar locks were constructed in the canal to compensate for the 260 foot difference in elevation between Sebago Lake and sea level. Traces of the old canal, abandoned since 1872, can still be seen at various places between Sebago Lake and Portland. This lock remains as a service to pleasure boats and a reminder of a bygone era. 1791 - Canal Considered
