Temperatures in the south exceeded 90 degrees this weekend with the night time lows remaining above 70 degrees. These temperatures, in conjunction with low rainfall, can lead to rapidly rising water temperatures. This is a recipe for lethal water temperatures for trout. If you practice catch and release and continue fishing freestone rivers and streams when the water temperature gets too high, you run the risk of killing the trout you intended to safely release. If you are a catch and keep fisherman, you might be wasting your time as fish concentrate more on surviving than eating.
