Ok, I'm new to the WWF, I admit it.

But us trout fishers use the stream themometer as a major tool in deciding how and where to fish. Surely the tool has its uses in the warm stuff.

I am, in particular, thinking about those river smallies -- 'cause I'm going after them this season. Are there key temperature milestones that tell you it's time to get out there?

Or maybe it's all bigger water and therefore basically a time of season deal?
