Late July, Some Still Spawning – Summary

Photos at end of post show a few instances of ‘spawning shock’ still underway in late July—potentially indication of a deferred spawning season in contrast to other cutthroat strains.

Hello Shannon;

Just a note to follow up a bit regarding the Alvord Phenotypes in the ***** system; and to thank you and your team again for the work and effort involved.  (We’re still recovering a bit from “hopping” from basin to snow zone to basin to snow zone to basin to snow zone to basin – then finally over the cascades home.)

A few photos are imbedded below (different cameras, angles, etc.)  We’re still looking forward to a few photos hopefully to come this way from Idaho.

The first three pictures below are from the first day (no clips were taken of these), though there may have been one that Dan and Kurt caught near the end of the first day that they took a clip from.  There was another one that Kurt brought to the tank on the second day that you may have a photo or two of?

I thought that we’d forwarded some of Joe’s comments to you (below) when we forwarded the brief video clip, but realized later that we hadn’t.  Essentially, it is the thought of possibly utilizing ***** Creek as the home for the Alvord phenotypes.  (What we viewed this time on the east side of the Pueblos did not seem at all suitable as a refuge for Alvord cutthroat trout.  We’ve walked virtually all of the Willow Creek system, and the lower part of Little Cottonwood.  The ravages of spring flooding and the lack of water in late summer were enough to dissuade us from considering them of any potential utilization for this project.)

We had thoughts along the same lines as Joe, that possibly ***** creek is the best refuge for the Alvord cutthroat trout phenotypes at the present time…  It would be great if there seemed to be an easy solution.

Have you had any other thoughts or potential solutions as to how to handle the Alvord phenotypes?

Hopefully your work near McDermitt was productive… We did catch a few Willow Creek cutts (and a few nice sized redbands from the Trout Creek system while there), and would have perhaps pursued Foster Creek redbands — but a seemingly “cantankerous rancher” caused us to divert from that plan.

We’ll look forward to chatting more when time permits, and we anticipate being able to construct a few thoughts; but for now we’d best sign-off.  Please drop a line when you can, and please let us know if of any additional support that we can provide.

Very nice!   The phenotype seems unmistakable as Alvord cutt.   I hope the simplest explanation can be the best on in this case.

Best regards,

Joe T.

Yes, it would seem at least on the surface that the best place to keep the trout is right where they are!    I wonder if some kind of depletion shocking would ever be considered, to remove anything that didn’t look like an alvord. …If they’ve survived this long, and they still look like alvords, what the heck?   Of course, you’d never get everything out of there, and I’m not sure if one could tell the young trout apart either.

Too bad about the Pueblos, but dead cottonwoods mean no surface water because the water table has dropped below the roots of the trees, shallow though the roots may be.

Best regards,

Joe T.
