EPHRATA — Salmon are making their way past the Wanapum and Rock Island dams after changes were made in fish ladders because of the lowered reservoir behind the Wanapum Dam, which is on the Columbia River near Vantage.
The Grant and Chelan County Public Utility Districts made the changes in May as part of the response to a crack found in the Wanapum Dam.
The news website iFIBER One News reports the ladders were tested with 250 fish released with tags. All the fish made it past both dams on their way upstream.
