Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
I am debating on what is best thermometer to get for measuring stream temperatures. I looked at a couple of older threads on other forums and there wasn't anything clear cut. Some are using cheap kitchen-type thermometers, some are using the mercury stick-type thermometers made specifically for use in streams and lakes and others are using more expensive digital thermometers. Any suggestions?
