A Brief Visit
Guard Locks on the Pawtucket Canal
Guard Locks on the Pawtucket Canal is the entryway to the canal
system and contains both a lock chamber for transportation, and
sluice gates for water power. This site is probably best know
for the "Great Gate", seen here on the left, a 21 ton
wooden gate completed in 1850. This gate was used in 1852 and
1936 to save the city from devastating floods. |
