Yes, I pay close attention to water temps while trying to decide areas to target for all species. Just by looking at the graph you posted, you had a 12 degree drop in just 5 days. That alone could really impact your fishing. Trout may love the drop but the muskies could go lay down for a few days.

The relationship between temperature/dissolved oxygen and the oxygen requirements of the species you are chasing has been important for me over the years. For example, if walleye fishing your area when the temps were 80 and knowing walleye like temps near 60, I would likely be checking areas adjacent to moving water. That is where the highest oxygen levels will be and likely have tons of food around.

When comparing lakes to rivers regarding oxygen levels, things can get a little weird.
