​Trout Activity and Water Temperature

Trout are cold blooded. As such, nothing affects their activity more than water temperature as their metabolic rate is controlled by it. As water temperature rises and fall, so does the metabolic rate.

Each species has preferred range. Char species like bull trout, arctic char, and dolly vardens prefer a colder range. Rainbows and brown preferences are warmer. This is you only see certain species in far northern climates and not others.

With winter upon us, water temperatures drop, as does fish activity. With the colder water and slowed down metabolic rate, fish simply don’t require as much food. They will eat, you just need to temper your expectations. I actually really enjoy fishing this time of year. Not a lot of people on the water, plenty of peace and tranquility, and the anticipation of a take can be exhilarating.

Though it may seem a long way off, elevated temperatures during summer months are not good for trout feeding activity. Water above 70 degrees begins to stress the fish. You really should leave them along at these temperatures. Early morning or late evening if you must, but don’t forget your thermometer.

That’s it for now my fishy friends. Please remember, pack it in, pack it out. It’s up to us to care for our waters.
