If they can find themselves some shitplant outflow there is a good chance they can survive the summer months. I think those outflows are usually pushed out around 50Â°F - 55Â°F.
Thanks for the report JM, but I was out Sunday on the same river and found the smallies to be rather active hitting swimjigs with a decent retrieve with the current. Just had to find the deeper water and work the pools.
I wouldn't mind tying into one or two of those holdover bows on my 4wt.
