It's not just the Vedder though Dave. The Stamp is having the worst year on record I believe. The hatchery fish component is non-existent. On the actual stamp I still haven't caught a hatchery fish. Of the 25-30 fish I've beached, all have been wild, and the other 30-40 that I didn't get right to hand appeared to be wild as well (many were within 5 feet of the shore when they were lost).
Overall though, the whole system is suffering. I wouldn't say the wild returns are anywhere near what they should be. They actually stopped taking brood on the Stamp because there is so much concern over how the wild fish are doing, and they no longer want to remove wild spawners from the population. I have also fished a large number of other rivers on the island this year, and all of them, including remote north island flows are suffering it seems. The only one doing well is the Cowy.
An interesting fact that another angler pointed out to me,... and I have found to be true as well this year, is that the fish are above average size for the most part. I have caught VERY FEW fish in the typical 6-7 pound range (for the stamp), and it seems to be the same everywhere (out on the island any ways). Most fish being caught by me and my buddies seem to mainly be 9-12 pounds. In my mind, those 6-7 pnd fish would be the first time returning fish, and anything bigger would be older fish returning for the 2,3,4 time. Would be interesting to see, but it seems like something may have happened to the 1st year age class of fish this year.
Here's hoping for a good late push of all the fish that haven't showed up all season...
