Question 20

All of the following statements about the connections between the Ogallala Aquifer and High Plains agriculture are true EXCEPT:

Accepted Answer

A) In some areas of the High Plains, farmers are drawing water from the Ogallala Aquifer as much as 40 times faster than nature replaces it and have lowered the water table more than 30 m (100 ft)in some places. 
B) Most hydrologists predict that groundwater will eventually drop in all areas of the Ogallala to a level uneconomical to pump so High Plains agriculture will eventually have to change back to dry land agriculture as it was before the aquifer was pumped. 
C) The High Plains produce about 15% of the nation's grain crops and almost 40% of its livestock using approximately 30 percent of the irrigation water used in the United States. 
D) As there is not that much urban development in the High Plains, the recharge zones for the Ogallala Aquifer are unaffected and thus if managed appropriately, can in fact recharge the aquifer adequately to keep up with current withdrawal rates.
