Comment in Fish Talk: Had tons of fun catching Chinook out of Anderson Ranch this summer. Are the initial plant of 35,000 spawning this year or next?

I've got good news and bad news for you.
First the good news: This will probably be the first year that earlier plantings of fall Chinook will be maturing and attempting to spawn in the South Fork Boise River. Fall Chinook have been stocked many times in Anderson Ranch Reservoir and maturing adults have never successfully reproduced in the South Fork Boise River or Fall Creek. The fall Chinook population is totally supported through our hatchery stocking program. There are currently 3 year- classes of fall Chinook in Anderson Ranch.
Now, the bad news: Fall Chinook are stocked in Anderson Ranch and other reservoirs around the state as a fish management tool to reduce over-abundant kokanee numbers. They are a very efficient predators on kokanee. The bad news is - they may have been too efficient because we observed very few kokanee spawning in the South Fork Boise River, this fall. We probably won't stock fall Chinook in Anderson Ranch Reservoir in 2017. The reduced numbers of kokanee remaining in Anderson Ranch may effect survival and the condition of fall Chinook remaining in the reservoir. This will translate into fewer fall Chinook in the fishery, next year.
We went to Brownlee (Reservoir) 6/18 and caught a lot of crappie and small non keeper Bass. Reservoir is full. Crappie were fairly aggressive on their bite.
Thanks. We've had many recent reports of 8-10" crappie being caught in about 20' of water. Evidently, they are beginning to feed after an early spawn. This bodes well for crappie fishing in Brownlee next spring. We would anticipate 2"+ of growth if conditions are right. Bass populations and size structure in Brownlee are cyclic. We will go several years with an abundance of 11 3/4" bass and all of the sudden they grow to 15 - 16" in a single year. More than likely in response to a change in forage. DP
Fished Lost Valley Res. north of Fruitvale this past Friday 6/10 .....fishing was slow for trout as it was for most anglers that I talked to.....we trolled and bait-fished for trout....instead we caught many perch in the 4-8 inch range. Beautiful day on the Lake that is as full as I have ever seen it.
Thanks for the note, Lawrence. We've tried to eliminate perch from Lost Valley Reservoir on several occasions - but they just won't go away. Glad the weather was great and you enjoyed your trip to one of Idaho's scenic fishing destinations.
