Large amounts of cobble and gravel that have accumulated upstream of the dam will be relocated back into the river below the dam. Approximately every other year, or as necessary, Avista moves the rocks, in accordance with federal, state, and local permits, which can damage the intake structure and interfere with power production. The project is expected to take up to approximately two to three weeks. Once the work is complete, the park will need to be closed again to disassemble the crane.
