300,000 gallons, .01/6.4 gals

so .01 * 300,000/6.4 is... $500.

How often do they need the water?

That's 500 for one acre so multiply by 300-400 for a typical farm and it cuts into already fairly small margins on farming

Corn will need about 24" of water each crop. So, if there is no or little natural rain, two acre-feet of water per acre. There is no concievable method of transporting such amounts inland. It would require energy enough to reverse the flow of rivers.
