Lower Granite Navigation Lock Crack Repair

The navigation lock at Lower Granite Dam is the final link in the inland waterway connecting the Pacific Ocean to the ports at Lewiston, Idaho and Clarkston, Washington. It has been in service since 1975. Navigation lock Monolith 29 is located on the downstream end of the lock on the south side. It is adjacent to the gate monolith, and contains the culvert discharge valves and miter gate machinery. A crack was noted in the roadway deck and the service gallery of monolith 29, and has been monitored regularly since its discovery. The crack width does not vary with lockages, and has grown slightly over time with January peaks increasing from about 0.04 inches in January 1990 to 0.12 inches in January of 2017. This crack is evident in both culverts. The work in this project involves sealing of the crack in the culvert during the 2018 navigation lock maintenance outage, and installing anchors for structural mitigation. Work will be performed in a vertical and horizontal culvert, requiring crane access or other methods for support of personnel to access the work areas. The work area will be unwatered, however the Contractor will be required to divert minimal water as required in the work area.
