Slate Creek Aquatic Organism Passage


Project Profile

Materials & Equipment 128”x83” Arched Culvert Replacement Project
Location: Hill City, SD
Owner: Black Hills National Forest & Rocky Mountain Region
Consulting Engineer: Black Hills National Forest & Rocky Mountain Region
Application: Watershed rehabilitation and aquatic organism passage
Special Project Elements: The washed-out culverts were contributing sediment into the stream and impeding aquatic organism passage. The newly installed culvert allowed free movement of aquatic organisms and reduced sediment input into the creek.

Project Challenges

High stream flows in June 2015 washed out two undersized culverts on Slate Creek Dam Road. A road closure was put in place for safety reasons, but vehicles were fording the creek causing resource damage.
