Temperature and water clarity of the Delaware River

The Delaware River up near Philly peaked this summer at about 75F. This is about 10F less than the past two summers, when water temp went up to 85F. Water clarity is also much much better. I can easily see the prop and skeg on my outboard, and can see down about 2' on my transom mounted rudder.

My guess is that the lower temp has suppressed algae growth. I have seen no blooms at all. The river currents have always broken up blooms, but in past summers you could see remnants of broken up algae blooms in the river.

I am not sure why the lower water temps. My guess is that more rain in the upstate reservoirs has kept the water management people spilling cool water into the river watershed. Plus, generally lower temperatures overall (only a few days hit 90F).

How have water temperature and clarity been in the Chesapeake, LI Sound, etc.?
