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
7. Pressure/sprinkler or sub-irrigation statistics by system type
8. Gravity irrigation by system type and water-management practice
   

   Tables 8-1 to 8-11 summarize farm numbers and gravity irrigated acres (by system type) for farms applying one or more gravity water-management practice, by farm size class, and gravity irrigated acres by specific gravity water-management practice (and their farm-size percent distributions).  more...
