Officials with the Illinois Department of Natural Resources say the agency wants to hire conservation police officers.

Applicants must have a 2-year degree with three years of consecutive experience as a police officer or a 4-year degree from an accredited university.

Then they'll have to take a swim test and undergo a background check, among other things. The job also requires weeks of training.

Conservation police officers enforce criminal, vehicle and drug law in Illinois state parks. Their duties include patrolling on Illinois lakes and rivers to check boating safety and watercraft registration.
