A man's body was discovered Thursday morning in a creek in a national wildlife refuge in Bloomington, authorities said.

Law enforcement officials were notified about 8:30 a.m. that a body was found facedown in the water in the Minnesota Valley National Wildlife Refuge. The body was first spotted by someone walking on a trail, according to emergency dispatch audio.

Bloomington police, the Hennepin County Sheriff's Office and the Medical Examiner's Office sent personnel to the scene south of E. American Boulevard and the refuge visitor center, and roughly a mile into the woods.

There was no immediate information on how long the body was in the water, the person's identity or the circumstances surrounding the death. However, the Sheriff's Office said in a statement, "At this point in time, no foul play is suspected."

The 14,000-acre refuge was established in 1976 and provides habitat for migratory waterfowl, fish and other wildlife species in an urban setting. It also offers environmental education, wildlife recreational opportunities and interpretive programming for visitors.
