Colorado is seeing some intense heat and arid conditions, so we wanted to share this graphic we made of when it's time to give trout a break! Water temperatures tell us so much about the conditions of a fishing spot and how the fish will be reacting. Once you reach past 68 degrees F, mortality chances increase, even with proper catch-and-release. A water thermometer is a cheap and easy tool to add to your fishing gear for your next outing.
