SIOUX FALLS, S.D. - Authorities say seven teenage boys were rescued from a small island of rocks at a Sioux Falls park.
Police say the boys swam out to the island in Falls Park early Saturday evening and were unable to return to shore because of the strong current created by a nearby low-head dam.
Rescue crews inflated a boat and brought the boys to shore in two groups.
Authorities say the boys were from out of state and did not know that swimming is prohibited in the river.
Police released the boys to their parents.
