Evanston, September 25

We are still in our September heat wave, air temperatures are still expected to get near 90. But the Lake has cooled anyway, although pockets of cooler and warmer water were still present the average was a consistent 67. Probably upwelling from the bottom of the lake was responsible. Not much in the way of waves today, we did see a lot of algae accumulation near the beach, some waves would have helped. Did a quick out and back because I was due at the dentist shortly.
