All your points well taken. "Negative public benefit" IMPO can be a good thing for a Lake that has had to withstand the intense pressure that this lake has had to endure. Entire Fly Fishing clubs descend on this lake for some unknown reason. I have been fishing this lake for over 50 years and can tell you the fishing has gone to hell!
Climate Change has raised hell with this lake as well as witnessed by many low water years followed by extremely hot summers. All you had to do was look at the summer kill on the bottom of the lake in the shallower areas. Year after year of far too much pressure plus the ills of Climate Change have plaid a huge role in the decrease in insect life which once sustained bows that averaged over two pounds and fought like Henry's Fork bows used to.
Now, the smaller, skinnier, bows, have been caught two or three times before the new "sparse" mayfly hatch occurs. I'll bet you can't name a single angler who has caught and released 20 or so fish on mids awaiting the calibaetis hatch only to catch another 20 fish on size 12/14 Dries!
All I am saying is this once, great, lake could use a break so it might heal with nature taking over for a few years. And, by the way, I am not hording this lake for myself. I have not fished the lake for many years and don't even intend to buy a license for the second year in a row.
