Lassen National Forest officials have announced a closure for segments of two forest roads, 26N08 and 26N35, to remove and replace three road-stream crossing structures.
The Storrie Aquatic Organism Passage Project is located on the Almanor Ranger District southwest of Humbug Valley. The project sites are all located within the Lassen National Forest in Plumas County.
Project site locations include National Forest System road 26N08 crossing Water Creek, NFS road 26N08 crossing Miller Ravine, and NFS road 26N35 crossing Rock Creek, Mount Diablo Meridian.
Elevations for each site range from approximately 4,400 feet (Water Creek, Miller Ravine sites) to 6,030 feet (Rock Creek site).
“The arch culverts being installed at the three road-stream crossing sites will allow for aquatic organisms to move freely between habitats upstream and downstream of the crossing structures” said Deb Bumpus, Forest Supervisor.
“Additionally, the arch culverts will improve the resilience of the crossings to 100-year floods.”
There are approximately 0.8 miles of perennial aquatic habitat upstream of the Water Creek crossing, 1.2 miles upstream of the Miller Ravine crossing, and 0.5 miles upstream of the Rock Creek crossing. The project is expected to be completed by November 15th, dependent on site and weather conditions.
