depending on the severity of the winter over the past 25 years I have

by the prevailing westerlies, piles up against the ice boom placed at
the entry to the Niagara River

Sage advice.

Also included in that ice are tree trunks that have come loose over the
winter and drifted down the Great lakes chain.

In the Pacific North West, they are called loggerheads.

On Lake Eire, the usual comment is Son-Of-A-Bitch, hope that f**ker didn't
hole the hull.

BTW, that boom across the river is there to protect the docks on the Black
Rock canal.

It's nice in that part of the country during July & August.

Been there, done that.
