(AP) — A proposed groundwater allocation plan is worrying several southeast Nebraska farmers.

More than 100 people attended a Tuesday hearing about the proposal at the Upper Big Blue Natural Resources District office in York.

The district oversees groundwater and other natural resources in Adams, Butler, Clay, Fillmore, Hamilton, Polk, Saline, Seward and York counties.

The district in 1990 set a groundwater trigger level for imposing limits. The current allocation proposal is 45 inches over five years, which would be imposed in 2015 if spring 2014 tests show the trigger level has been reached.

Farmers fear that such restrictions and other proposed regulations would cause crop profits to dry up.

The district board has no deadline for a decision and didn’t make one Tuesday.
