The enormous energy released by the catastrophe at 12,500 yr B.P. could have heated the atmosphere to over 1000°C over Michigan, and the neutron flux at more northern locations would have melted considerable glacial ice.

Is it just a coincidence that the date is eerily close to the estimated date of the Lake Agassiz great flood?

“Estimated date eerily close to the Lake Agassiz great flood.”

Actually 4 to 5,000 years is not exactly close. I suspect that if there was a boloid event around 13,000 years ago, that after a time, freezing built up especially around the edges and you had an “ice dam” effect wherein the Lake had several thousand years to grow until it busted out. There is also a similar event that apparently took place out west, (the Missoula Scablands, I think is the name, someone correct me if I got the name or place wrong) which had a very interesting program on public television. I think the age for that, and it was multiple events, was closer to Lake Agassiz than to the earlier “event?”.

I've done some reading about Agassiz and it's not altogether clear(to me) there was a catastrophic flood from Agassiz. There is abundant evidence of a gradual lowering of the lake level over a long period of time as the ice sheets retreated. I suppose it's possible, maybe even likely, there was a final dramatic emptying of the lake when the last of the glacial dams gave way.

Missoula on the other hand, apparently(?) had numerous fillings/emptyings during the last ice age. I don't know how that was determined, but the folks that study this stuff seem to believe it.
