Project Monitoring
~Stream Structure Monitoring~

     Instream structures placed for restoration are monitored annually in June by staff and volunteers. Structures consist of full spanning weirs, deflector logs, rock barbs, rootwads, toe logs, cover logs, log jams, etc. Structure monitoring parameters include bankfull width taken at the structure and structure location (right bank, left bank, or full spanning). Observations and measurements are taken immediately at the upstream and downstream end of the structure. Data is collected on dominant substrate, particle packing, and pool development. SFEG records the condition of the structure and its function. This includes noting any bank erosion or scouring.


Interns and volunteers learn how to monitor the status of in-stream structures at our restoration site in Klahowya Creek.

Engineered structures are designed to mimic natural logjams and fallen trees, such as this natural structure at East Fork Nookachamps.

Structures are cabled into place to prevent shifting during flooding.
In-stream structures, such as this one in Finney Creek, help create pools and cover for fish, help create meanders in streams, and help trap sediment and sort gravels.
