Mill pond

A mill pond is a body of water that is created by damming a river or stream, typically for the purpose of providing a water source for a mill. These ponds are often created to ensure a consistent flow of water to power watermills, which were historically used for tasks such as grain milling, sawmilling, or other industrial processes. The water level in a mill pond can be controlled by gates or sluices, allowing mill operators to regulate the flow of water to the mill.
