Of Interest: Black Rapids is a peaceful oasis in the urban sprawl of Ottawa. It offers a beautiful park like setting with large trees and verdant lawns. It’s one of only two locks (the other being Newboro) that were converted from manual to electric operation, the conversion here was done in 1969. It also features a flat overflow dam. Spring flooding caused problems with this dam, it had to be rebuilt several times, with the last major re-construction done (using concrete) in 1925.
Notes: No gas nearby

The photo clearly shows the relationship of the overflow dam, the waste water weir and the lock. Most of the water level regulation is done by the weir. Stop logs can be removed to allow more water to flow through the weir. Colonel By in his design of the Rideau locks had to take into account typical Canadian spring flooding. In more temperate climates, an overflow dam could take care of all the water level regulation. But the amount of water heading down the Rideau in early spring would scour the base of an overflow dam and eventually destroy it, so a weir is used to drop the water level above the dam in advance of spring flooding and to pass through most of spring flood water.
