Ah! Pretty sure that’s a stilling well to measure the river stage:

Cool. That explains the reservoir, too! Thanks! Provisionally solved!
Wild guess that it’s a pump.
Measuring water level maybe. I have a similar setup by the river
No immediate single idea.
I want to say a sleuce/overflow gate or valve of some sort.
Remote control and actuator in the top (or the control is in the separate cabinet you mention, and the modot is on top), with the vertical shaft down to the gate (or a protective cover around the shaft, cause that vertical pipe is massive if that is actually the shaft).It does look like it has welded diagonal bracing between the pipe and the structure (as opposed to the u-bolt clamping that seems the initially intended methods), as if some rotational force has previously caused misalignment.
Might be some sort of sensor tube, and the “high voltage box” is just an enclosure for the control systems. Doesn’t explain the added welded braces tho.
Any more pictures?
I think this fella’s figured it out: https://sh.itjust.works/post/64988214/26871936
What can I take pictures of that would help you?
It seems like a helluva lot of hardware just to report a water level.
What would the function of that bricked in reservoir be? I don´t see any gates there but I can have another look tomorrow. My dog likes to hang out there.
