Are those outfalls in the lower left?
The round one in the rock is an unknown outfall. It's never active and might be 'abandoned' as it's not listed on city GIS maps.
The red brick building is abandoned, just a hollow shell, and dangerous (1-2 deaths there). Water would have flowed, but not worth it.
The cave in the rock at water level on the right goes up to the building above it.
Also out of frame are 4 rochester urbex locations all within a 60 second walk of each other.
