Trinity ??
I don't think so......
When flows on the L.S. get to 10k...it's usually May.
Then they drop to below 10k by mid-Sept....sometimes earlier.
Not much steelheading on the T during the June/July/Aug/Sept. timeframe.
Not to mention, 'they' will only close the top 4 miles of a 30+ mile stretch of GREAT summer trout fishing. I've had good fishing all the way down to Corning during the summer. Very few, if any, guides will be on the T during the 10k cfs timeframe here on the LS. There is a TON of GREAT water that isn't "Posse Grounds".
The bonus to it all ???
Those of us who have small jet boats with oar set ups will still be able to move around up there, and drift/anchor/wade all the usual spots if desired, unless they close the 'ramp', which I don't see happening.
