Fantastic report, super inspiring of a not-well-traveled-place — and intriguing too!
I noticed your comment about the lack of piscatorial creatures in the watershed. I have long had an interest in this region but lacked the timing to get an overnight trip in for properly exploring a bit of the area. Spoke with the Whitewater rangers in the past about it, and they thought I would be better off spending the same amount of time driving up to the Eastern Sierras :)–I like hiking, I prefer it over driving!
Did you drop a line without success, or only not see any swimming while hiking by?
Also, have you tried your luck on the other forks for the same targets?
Thanks! Happy to chat privately too.
