Wis. DNR: Annual bacterial disease killed fish
MADISON, Wis. (AP) — State fish experts say a bacterial infection killed thousands of fish in Lake Delton.
Department of Natural Resources fish specialists investigated thousands of dead black crappie and white suckers that washed up ashore on lake properties late last month. The agency has determined a disease called columnaris killed the creatures.
The disease is common and typically occurs in late spring and early summer when water temperatures rise and fish are stressed from spawning and changes in water quality. It causes fatal lesions on fish's gills and skin.
The disease can't hurt humans, but DNR officials say people don't eat infected fish because other bacteria growing on the remains could be harmful.

How about running some city water pipe near the bottom of the pond to cool down the water. Not adding city water to the pond, but by making the city water running through the pipes would be cold water there and cool the water in the pond.

Columnaris is a very common fish disease -- if you have an aquarium you need to be aware of it. What's the big conspiracy, makr? I'm not sure what could be more serious than thousands of fish dying.

There is more to the story than just calling this a common disease when thousands of fish die.
It seems to me that this is indicative of a problem more serious than described in the report.
