Whenever the board finds that any county highway has been damaged or is in danger of being damaged by storm waters or floods, the board shall adopt all measures necessary to repair or prevent such damage. The board may condemn the right of way for, and may construct, flumes, ditches or canals for the purpose of carrying off such storm waters or floods.
The board may cause any expense incurred under this section to be paid out of the county general fund, or out of the funds of any road districts in which the highways are protected from damage or repaired by the work done.
