Irrigation Zone Map

Outside watering for lawns and gardens can place a significant demand on public water supplies.

Utah has six climate zones (excluding non-arable lands), which correspond with crop consumptive use and annual precipitation. In the northern mountains, the outside watering requirements would be quite low (Zone 1), compared with the southern part of the state where the climate is usually very warm (Zone 6). As a result, these use zones have different outside watering requirements.
