Blue sky it was, so, what would I see...
Doing an establishing shot of the focal point of the area, the old Yates Mill, I chose an angle that emphasized the reflected blue in the windows. I did not want to tilt the camera up to cover the height of the building (my vantage was low on the rocks), so I used a tilt/shift lens, shifting the lens upward. I leveled the camera, but unintentionally pointed it very slightly downward! I liked the very slight divergence of the vertical lines - it seemed to add to the imposing bulk of the old wooden structure, so I left it that way rather than refining the leveling nearer to exactly accurate. It's a pretty subtle difference, but if you're tuned into "architectural" verticals you'll see it, and if not, you might feel it.
Moving further away and to a higher vantage point, I used a longer lens to isolate an interesting part of the structure and contrast it with the trees.
For this image, the extreme contrast of sunlight and shade was tricky to tame, but the shadows added to the composition.
As the sun got lower, there was a bit of gold in the light, enhanced by reflection off the wood. I chose to exaggerate this to contrast it with the blue tones.
There wasn't a lot of fall color in the leaves, but across the pond there was a patch of red standing out from its surroundings. The shape of a dark branch balanced things, and a long telephoto included just the area I wanted in my composition.
The view across the pond was serene. Here the angle is such that the sun was blocked by a tree limb in direct view, but shows in the reflection.
I suspect that some gorgeous sunset colors may have been on the way, but I needed to leave to attend a pre-concert reception for a group of patrons, after which I had a difficult concert to perform.
In my last few moments I tried an abstract reflection shot.
And a parting shot across the water when a pedestrian in bright clothing caught my eye.
