Lassen National Forest officials have announced the reopening of national forest system roads 26N08 and 26N35 following the completion of the Storrie Aquatic Organism Passage Project.
The Project sites were all located within the LNF in Plumas County, including National Forest System road 26N08 crossing Water Creek, road 26N08 crossing Miller Ravine and NFS road 26N35 crossing Rock Creek.
Arch culverts were installed at the three road-stream crossing sites allowing for aquatic organisms to move freely between habitats upstream and downstream of the crossing structures.
“The project completed two days earlier than expected and within budget by Hooker Creek Inc.,” stated Todd Orange, Project Engineer, LNF.
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. Additionally, the arch culverts improve the resilience of the crossings to 100-year floods.
“These new structures give the capacity to pass the water and debris at this 100 year storm design flow,” said Deb Bumpus, Forest Supervisor, LNF. ”The new design improves aquatic and riparian habitat conditions by reducing the stream channel incision and bank erosion downstream of the crossings.”
