Monitoring water temperature is crucial for successful trout fishing, as it influences their behavior and feeding. Using a submersible thermometer is recommended for accurate readings. Optimal fishing occurs between 50 to 60°F, while temperatures above 65°F stress trout, warranting restrictions. Adjust techniques and focus on specific conditions for best results.
