Long Physical Description:
The historic irrigation ditch system located in Montezuma Well unit runs from well outlet along Beaver Creek through monument. The system contains prehistoric and historic elements. For the first 150m, it follows the path of the prehistoric irrigation canal (AZ O:5:94) and then diverges into two separate historic irrigation ditches. This ditch system has a series of headgates, flow rate meters and water level meters. The ditch system naturally becomes lined with travertine deposits from the high mineral content of the Well water. The system carries the water through the monument for irrigation purposes and further on past the monument boundaries to users downstream. The average flow is approximately 2 cubic feet per second or 1.3 million gallons per day.
