Black Sluice

The Black Sluice is the name given to the structure that controls the flow of the South Forty-Foot Drain into The Haven, at Boston, Lincolnshire, England.

The ensuing battle with the population left the works destroyed, and this seems to be the origin of the name Black Sluice.

[1] The lock which gave passage past the Black Sluice fell into disrepair after the second world war, but was restored to full operation in 2008 as part of the Fens Waterways Link scheme to improve navigation through the fens for pleasure craft.

Connection to Lincoln is further restricted by the size of the lock at the Grand Sluice, which is just over 13.7 metres (45 ft) long, although longer vessels can pass through at certain states of the tide.

[6] Black Sluice Lock is not permanently staffed, so bookings for transit need to be made a minimum of 24 hours in advance.
