In October 2009, giant sandbags were placed along the levee from Fort Dent through Kent and the Green River Trail was closed to cyclists. The sandbags mitigated the flood potential due to a weakness discovered in the Howard A. Hanson Dam following a January 2009 storm. Repairs strengthening the partially earthen dam by the Army Corps of Engineers have reduced this flood threat significantly. In September 2012, the Green River Trail was reopened following the removal of all giant sandbags.
