Same with smaller streams in the area. On the way home from playing age-level basketball (badly) this morning, we saw a car on a local creek that was likely 70 degrees or higher -- even had a "wild trout" license plate holder. Unless it was someone new to trout fishing, he should have known better. Many (most?) of the trout he caught and released, if he was a c/r fisherman, will likely die sometime soon.
Probably better to go bass fishing or head north to find streams there with decent flows and temps. But, looking at some of the USGS reports, those creeks might not be ethical to fish either.
Anyhow, you are probably better to let the LJR alone till we get a nice stretch of much cooler weather.
