Much of the Columbia River shoreline in Washington is open to the public. One big exception is the new shoreline exposed by lowering the reservoir behind the Wanapum Dam while the Grant County Public Utility District repairs a crack.
Sheriff's deputies and state Fish and Wildlife agents are enforcing the shoreline closure between the Wanapum and Rock Island dams -- a stretch generally between Vantage and Wenatchee.
The Wenatchee World reports the closure is necessary to protect archaeological sites from looting and to prevent visitors from getting stuck in the muck.
Two ancient skeletons exposed by low water have been found near Crescent Bar.
Officers are giving warnings but trespassers on the shoreline could be fined up to $1,000.
