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
   

   Tables 7-1 to 7-16 summarize farm numbers and total acres irrigated using sprinkler, drip/trickle, or sub-irrigation system types (and their percent distributions), by farm size class. Table 16 summarizes acres irrigated (by farm size class) for a more water-conserving, pressure irrigation technology (all low-pressure sprinkler and drip/trickle systems).  more...
