Western Irrigated Agriculture: Tables

All tables summarize data by farm size and State

1. Total irrigation values, all irrigated farms
2. Average irrigation statistics (per farm)
3. Average irrigation statistics by water source (per farm)
4. Irrigation wells and pumping costs by energy source
5. Average irrigation maintenance and repair costs (per acre)
6. Gravity irrigation statistics by system type
   

   Tables 6-1 to 6-13 summarize farm numbers and total acres irrigated using gravity irrigation systems (by type) and by farm size class (and their farm-size percent distributions). Table 13 summarizes acres irrigated (by farm size class) for a more water-conserving, gravity irrigation technology, i.e., furrow gravity systems using pipe (above ground or buried) or lined open-ditches for field water delivery.  more...
