The mill race (also mill-lade or just lade)[2] is a channel that carries water from its source - a hydroelectric dam or river — to the site of a mill using a waterwheel. This mill race directs the water to the waterwheel - either underneath it in the case of an undershot waterwheel or at a midway height in the case of a breastshot waterwheel.
The race can be a few meters in length to several kilometers depending on how far the water source is from the site of the waterwheel. A single race can serve one or many wheels.[3]
The phrase mill race is only used to describe the water channel directing water to an overshot or breastshot wheel. For an overshot waterwheel, a special channel must be built to direct water over the top of the waterwheel. For this type of channel, a flume is used instead.[4]
