Locking through the Lower Granite Navigation Lock & Dam, located at Snake River Mile 107.5, may require additional time beginning 25 February
2016 for inspections of a tainter valve.
Lower Granite staff will inspect and measure components of the valve for future replacement. While the valve is out of service, vessel lockage time
may lengthen by approximately 15 to 20 minutes (plus or minus).
For additional information, call Operations Division at (509) 527-7113 or (509) 527-7115.
