Union Canal
After entering the reservoir at the Big Dam in Swatara Gap, water from Swatara Creek came down the branch canal to the Water Works, 3.7 miles southwest of here. At that point it was raised by water wheels and steam pumps and carried by a feeder tube to the summit level near Lebanon. From there the canal descended eastward to Reading and westward to Middletown.
