Locks and Spillways
Locks were used to overcome elevation differences along the D&R canal. Many of the locks are still present along the canal route; however, the lock gates have been replaced on the upstream side with small dams and water outfalls. The downstream gates have been removed, so the water in the locks is level with the water on the downstream side. Some of the locks have been buried or removed due to construction projects in the vicinity of the canal.
A number of spillways, which drained excess water from the canal into nearby waterways during periods of heavy flow, are located along the canal route. Spillways are evident as a dip in the tow path along the canal. Some have paving stones spaced closely enough for mules to walk, but are impassable for bicycles. With the flow stopped, species typical of stagnant water live in them.

Famous quotes containing the word locks:
“If courtesans and strumpets were to be prosecuted with as much rigour as some silly people would have it, what locks or bars would be sufficient to preserve the honour of our wives and daughters?”
—Bernard Mandeville (1670–1733)
