There is similar work going on to restore fish passage underneath I-90 near Issaquah, Washington. Although in that case, the part of the streams that's currently inaccessible is less than a mile for most of them, and 2 miles for one of them. It's a major undertaking to restore a stream bed or channel underneath the interstate.
This will benefit Kokanee Salmon, a kind of salmon that spends all its life in fresh water and does not migrate to salt water like most salmon.
In Lewis Creek, they currently have access to only 1/2 mile of the creek, but in 2021 there were about 1000 of them returning (from Lake Sammamish) to spawn.

Excellent work as expected from NOAA's Habit Conservation team. These fish ladders are such an excellent investment in the future of our inshore fisheries, I wish it were easier to express that to citizens and corporations,

Silly question but if I remember correctly salmon go back to reproduce where they spawned. This suggests that once access is cut up a river, that location loses its salmon (can’t get there, so they don’t reproduce?)
Do they artificially reintroduce the salmon once access is restored or does that “neighbourhood” of salmon somehow survives and keeps trying every year ?

My lab does fish population monitoring around the Bay, including the mouth of Alameda creek, so I suppose one entry in the "good problems to have" is another potential spot where we could start catching steelhead and chinook, given that we have an extremely limited allowance.

Such good news - for those looking for a relaxing hobby fly fishing is an excellent sport to get into. You spend all day standing in a river trying to out smart some fish and trout are exceptionally beautiful creatures up close.

It's so refreshing to see a big company like PG&E reach out to help restore fish breeding ground even if at base level it was a win win situation.

> PG&E, Oliver de Silva, and a Bay Area foundation provided the rest of the funding to complete the project.
Why was a 'Bay Area foundation' referenced yet left nameless? I never understand the logic behind this convention..

What an awesome project. It’s nice to see something ambitious and infrastructure-related actually completed.
