So, with the info you provided, they admit there's far too much stray current being discharged than the 24Volt DC oriented anodic system can handle.
In your searches, did any of them mention what the current carried by the whole system is supposed to be? (such as 740 VDC, 1200 amps, as a wild, non realistic example.)
Guys, part of Lake Washing Machine is brackish, due to the canal, right ?
For those of you who deal with Engineering interfacing with Conservation and wildlife, should Sound Transit be charged with violation of ESA? Or has the current administration castrated that too, in which case, pretty much nothing will happen anyway.

Search results cannot find any publicly available values on the actual current into the anodes. Sound Transit environmental reports describe it as a low-level electrical current.
Sound Transit also claims the highest measured electrical field intensity around the ICCP anodes is 26.2 µV/cm DC, and typical Intensity: 13.1 µV/cm DC. They say that is roughly 4,000 to 40,000 times weaker than the threshold needed to cause physical injury, muscle tetany, or death. (???) But fish were and possibly still are being killed. Maybe a chemical reaction from electrolysis
(Hoping a resident engineer with relevancy steps in here.)
just erased my post, think I found the answer to my question on what the units of measurement are.
I don’t know how accurate my search was but it said that 1V/cm will stun fish. I guess that’s is the voltage that could be measured between two points a centimeter wide. They apparently use 1000 volts when stunning fish, and if those probes were 1000 cm wide that would give you the 1V/cm. That’s how I understand it, I could be wrong,…
So 26.2 Microvolts/cm is quite small.
There definitely more to this story. Something fishy is going on we’re not being told…
