Do any of you take a thermometer with you and if so what would you say is the optimum range for both still water and river?

I don’t, but have been thinking about getting one as my local river gets water released up stream to keep the canoe boys happy and I can feel through my breathable`s the difference from the day before and have noticed the fish not playing out when this happens.

Brown Trout below 68 f and rainbows below 67 f. I know you catch trout on many streams and stillwaters when it's warmer but these are averages over the years when I believe the fish hit best.

I used to in the US because the water temp can get really warm in the summer and when that warm you shouldn't be fishing.

For me, I prefer stream water to be 55-65. In that range, the fish will be active, the bugs will be out, and stressing the fish (catching them) isn't goint to kill them. Above 65 and you're pushing the limits. Above 70-72 and you really shouldn't be trout fishing C&R.

In lakes I suspect that the C&R aspect is the same, though I have no basis for ideal temp from a catching perspective.

Yes, I take one and it is marked off with optimum feeding temps, max survival temps and min survival temps using electricians tape to save memorizing the individual temps... will try and post pic later

Try this: -




OMG it actually works after 3rd go......
