Police say at least 16 people have been killed in flash floods at a state park in western Arkansas. Reports say more than 40 people are still unaccounted for.
The park is situated in a valley between two heavily forested hills, near the Little Missouri River. The "little Mo" watershed got hit with 5" to 9" of rain within a very short period of time. The water level went from 3 feet to 23 feet between the hours of approximately 11:00pm to around 3:00am.
Bill Sadler from the Arkansas State Police said they would continue rescue efforts a long as necessary. The park does not require campers to register, so it was unclear how many people remained missing or if any people managed to escape the racing waters to pull themselves onto the shore.
