Editing Chesapeake and Ohio Canal (section)

===Levels===
The stretch of canal between locks is called a [[Canal pound|level]]. Canalers called these levels by their lengths; for instance, the longest level was the 14 mile level, which was about 14 miles long, and ran from Lock 50 (at 4 locks) to Lock 51 in Hancock. Some levels had additional nicknames (since some had similar lengths), e.g. "Four Mile Level below Dam 6", "Four Mile Level Big Slackwater", or "Four Mile Level of the Log Wall" (which is between locks 14 and 15, includes Widewater, Anglers, Carderock, Billy Goat Trails B, and C, and the downstream entrance to Trail A, all connect on that level). Levels less than a mile between locks were called short levels.<ref>[[#hahn-boatmen|Hahn, Boatmen]] p. 55</ref> Waste weirs and [[Locks on the Chesapeake and Ohio Canal#Bypass flumes|bypass flumes]] at the locks helped control the height of water in the levels (see below about waste weirs).
