Glacier-Gallup Creeks Levee Repair

The left (west) abutment of the Glacier Creek bridge is currently protected by a levee built in 1962 after a damaging flood.  The levee has two primary functions: preventing a major channel avulsion toward the narrower Gallup Creek bridge crossing and protecting the left abutment of the Glacier Creek bridge from erosion. The levee has been repaired occasionally over the last half century. ln November 2018, an approximately 100-foot long portion of the levee was partially eroded during a flood. The eroded portion has expanded to approximately 170 feet as a result of further damage sustained during the February 2020 and November 2021 floods. This bank is vulnerable to significant bank loss because of this damage. Work is underway summer 2022 to repair this damaged section of the levee.
