GREAT FALLS – Emergency crews were staged along the Missouri River from Black Eagle Dam to Giant Springs State Park in Great Falls on Monday morning.
According to Cascade County Sheriff Bob Edwards, dam workers saw a person in the river coming toward the dam.
They say the person went through dam.
Edwards said the operation began as a rescue, but due to water levels and temperatures it is now considered to be a recovery operation.
They do not yet know if the person is a man or a woman.
