“We have information that the state water board attempted to conduct a criminal background investigation on one of our board members,” said attorney Daniel Kelly. “We thought that was highly unusual.”

The irrigation district has subpoenaed the state board.

“The subpoena that we sent to the state water board to understand under what authority they can conduct those background checks and number two what they learned from those background checks,” Kelly said.

The irrigation district wants to know how far the state is allowed to go.

“That’s what we’re trying to find out. Is this highly unusual or is this something the state agency does on a routine bases? I just simply don’t know,” he said.
