Water wheels were used to power sawmills, grist mills and for other purposes during development of the United States. The 40 feet (12 m) diameter water wheel at McCoy, Colorado, built in 1922, is a surviving one out of many which lifted water for irrigation out of the Colorado River. Two early improvements were suspension wheels and rim gearing ...

Typical efficiency of water wheels exploiting only the kinetic energy was around 30%. [1] These wheels are called stream water wheels, or kinetic water wheels. Instead, undershot water wheels are used in low head sites, like less than 1.5 m, and they also exploit the potential energy of the flow, with efficiencies of up to 84%.

Mill Springs Overshot Waterwheel located at Mill Springs Park. The current mill built in 1877 on the site of a previous mill. Currently owned and operated as a park by the United States Army Corps of Engineers. The wheel has a diameter of 40 feet, 10 inches, and a breast of three feet.

It is a large wheel fitted with boxes, which in the first design, encompass the whole diameter of the wheel. Holes are bored in the boxes to allow water into them, so that as a box dips into the water, it enters and is raised as the wheel turns. When it reaches to the top of the turn, the water runs out into a channel.
