Even though i live in OR. We too, are facing the same problems. This sounds like the chicken or the egg, which came first. Distruction of natural spawning grounds or over harvesting. It's a no brainer. Both. Having worked closely with Weyco. in OR, I was able to see the destruction that was caused in the 50's, 60's and 70's before there were any laws that curbed past logging practices. Many (most) of the natural spanwing ground has been touched by logging. Not all destroyed, but touched. This combined with fewer returning wild fish due to over harvesting in the same time period (50's-70's) results in low numbers.
Coos Watershed is now working closely with Weyco. here in SW OR. After working with both sides of the problem, I can honestly say that it is getting better. Is the wild fish population increasing? Probably not, yet. However, it will with continued efforts from us.
I teach at a local elementary school, but donate a ton of my summer time to research for both Weyco., Coos Watershed and the local ODFW. Along with the STEP programs in 3 different streams and the Elk river hatchery. Not to mention brood stock collection on the SF, EF and NF of the Coquille river.

My motivation is my 5 year old son. I want him to be able to catch a wild steelie or Spring Chinook.

It is getting better, but we must pay attention, and act accordingly.
