Wanapum State Park will be closed until further notice because of a crack discovered in Wanapum Dam earlier this month, the state parks commission announced Friday.
To relieve pressure on the dam, the Grant County Public Utility District lowered the water level.
The PUD also closed all beaches and access to the Columbia River above the dam to protect sensitive cultural resources and to help ensure public safety.
Customer service representatives from the state parks reservation call center are phoning customers with reservations at Wanapum State Park for dates through July 7 to notify them that their camping reservations have been canceled and to refund their money.
Never miss a local story.
Customers can reach the call center by calling 888-226-7688.
Because the beach and water access are integral to the park, all access, including walk-in access, is closed, said the parks service.
It’s not known how long reservoir levels will remain low or when the park could reopen.
Gingko Petrified Forest Interpretive Center, a nearby day-use facility in the Wanapum area, remains open.
Campers with reservations at Wanapum State Park for dates beyond July 7 may keep their reservations in place if they wish, in case the park reopens, or they can cancel at any time this summer for a full refund, said the state.
