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:
“So Lycidas sunk low, but mounted high
Through the dear might of him that walk’d the waves,
Where other groves and other streams along
With nectar pure his oozy locks he laves
And hears the unexpressive nuptial song
In the bless’d kingdoms meek of joy and love.
There entertain him all the saints above
In solemn troops and sweet societies,
That sing, and singing in their glory move,
And wipe the tears for ever from his eyes.”
—John Milton (1608–1674)
