Some local freestones are starting to push 70 degrees Fahrenheit already. That’s way too warm, too soon. As I’ve written about before, warm water is dangerous for trout.

Another option is to find waters that are naturally being cooled by aquifers. So, if you want to find more fishable trout waters during heat waves, read Colie’s blog post.
