In 2021 Trout Unlimited national did a comprehensive temperature monitoring effort on the Rogue River watershed.
The data is displayed based on Maximum Weekly Average Temp (MWAT). This statistic is often used by researchers to understand thermal habitat suitability for trout and other coldwater species. It is the highest average temperature for any 7-day period during the monitoring effort. Generally, for trout, an MWAT below 66 (Blue) is fantastic, 66-70 (Green) is good, 70-73.4 (Yellow) is marginal, and greater than 73.4 (Red) are not good temperatures for trout. Areas that have higher temperatures may still support trout populations but usually at much lower abundances. If you click on the site marker, a box will pop up that will also show the July average, which is the metric Michigan DNR uses to evaluate stream temperature.
Check before you fish! As water temperature rises the amount of dissolved oxygen available in the stream decreases. Fish need oxygen too, high temperatures and low oxygen levels cause stress on fish populations. Most trout species begin to experience stress around 68°F. As a good rule of thumb, avoid fishing when stream temperatures reach over 70°F.
