Frequently asked questions

It blew hard but barely rained, and the cellar took water. How?

The blow raised the harbor. Wind piles lake water against this shore, the outlet stops falling, and port-fill cellars wet from the ground with very little rain involved. What matters is the wind direction, not the rain total.

Ninety-six percent of this stock predates 1990. Does that change the October job?

It decides it. A 1941 cellar on port fill went in without an exterior drain, so once water is in the wall it leaves by evaporation rather than through a pipe. October's 4.78 inches of a 46.81 inch year goes into that fill and stays for weeks. Plant-era additions on the same houses joined roofs at angles that let harbor wind drive rain into the joint. The assembly is why the season lasts.

The harbor is ice-free. Why is the cellar still wet after October rain?

Ice-free is not low. The lake still holds the harbor. October rain on a held brook goes into port fill and 1941 walls. A clear harbor view from the pier does not lower the table under the house. A held lake still wets port fill after the view from the pier turns bright.

These questions come from the Dunkirk page.
