About half of the irrigated land in southern Idaho is furrow irrigated. With furrow irrigation, a
portion of the irrigation water runs off the tail end of the field. Some runoff is necessary to
adequately irrigate the whole field. In the Magic Valley, farmers run 20% to 50% of their
irrigation water off their fields into tailwater ditches. Twenty percent runoff is about the
minimum possible on the local soils and slopes. Fifty percent indicates poor management.
Average tailwater runoff from a furrow-irrigated farm is about 40% of the water supplied to
the farm.
