Culvert upgrades will cause road closures on the Republic Ranger District in the Colville National Forest

(PRESS RELEASE/Colville National Forest)

Beginning Aug. 17, through approximately September 25, culvert upgrades will take place on the Republic Ranger District in the Colville National Forest. Each culvert
upgrade will take approximately two weeks. The first will consist of Forest Road 5320 in the Scatter Creek project area, followed by the Sanpoil project area, which includes Forest Road 2054200, then Forest Road 2054.

The first culvert to be upgraded is located on Forest Road 5320 where it crosses Scatter Creek. This culvert is located near the intersection of Forest Road 5320 and Forest Road 53. Access to Ferry Lake and Long Lake Campgrounds will remain open during the upgrade period. After that upgrade is complete, two more culverts will be upgraded in the Sanpoil area crossing South Fork Ninemile Creek and Ninemile Creek. One culvert is on Forest Road 2054200 where the road crosses South Fork Ninemile. The other culvert is on Forest Road 2054 where the road crosses Ninemile Creek.




The culvert upgrades are part of the Aquatic Organism Passage (AOP) program that began in the 1970s to identify and correct passage problems caused by human-made barriers. These new AOP culverts will mimic the natural channel aquatic species use to pass through enabling them to access habitats they need at different times in their life cycles (spawning, rearing, feeding, sheltering) and under different environmental conditions (water too cold or too warm, floods, droughts, predators). Due to their construction they are less prone to plugging and other types of flood damage than traditional culverts.

This helps lower the maintenance cost and repair needs over the life of the culvert. During construction, these roads will be closed to reduce public safety concerns while the contractors are operating equipment.
