Description    


In the summer of 1998, Washington Trout (WT) and partners completed Phase I of the North Fork Stillaquamish (NFS) Engineered Logjam (ELJ) Project. Five ELJs were built at river mile (RM) 21 of NFS. Preliminary assessments indicate significant Summer Chinook holding habitat has been created & the ELJs have performed as expected. This project will implement Phase II of the North Fork Stillaquamish (NFS) Engineered Logjam (ELJ) Project. WT will construct 3 ELJs at approx RM 22.5, and perform post construction monitoring. The sub-reach where ELJs will be installed is a plane-bed channel with ample spawning area, but limited Chinook use. ELJs will provide vital holding habitat that will allow Chinook access to spawning areas. Holding habitat will increase at least 2 - 3 fold in this reach and direct the habitat away from an area of negative human impacts. Juvenile rearing will be enhanced & access to valuable off-channel habitat restored by project implementation. Long-term goals in phase II include the securing of conservation easements on adjoining properties. All necessary permits are in hand. Pre-project monitoring & construction preparation will begin 8-11-99. Instream work will be completed by 8-22-99. HPA expires 8-23-99. Post-construction monitoring will continue thru 5-31-00.
