Culvert
replacement
A perched culvert, like this one on Lewis Creek, can be a passage barrier for migrating salmon. |
One solution is to replace the culvert, placing stream substrate materials inside the new culvert, a technique referred to as "streambed simulation". |
Pringle Creek's new culvert installed with "streambed simulation". |

 This 8-inch corrugated pipe presented a passage barrier to coho salmon in Lake Creek, a tributary to Lake McMurray. |
 The new 4-foot corrugated metal culvert allows improved fish passage for Lake Creek coho. |

Bridges
SFEG partnered with the Trillium Corporation to remove this fish blocking culvert on Alder Creek in 2001. |
Replacing the perched culvert with this bridge on Alder Creek improved fish passage to nearly 10 miles of spawning habitat for pink, chum, chinook, and coho salmon as well as steelhead and cutthroat trout. |

Weirs
Log weirs installed at Powderhouse Creek in the Sauk Prairie to improve stream conditions by creating a series of steps for salmon. |
