Frequently asked questions
Why does October hit the valley floor harder than the hills above it?
The floor is where the catchment ends. Monadnock-side lots shed 4.86 inches of a 46.11 inch year down one steep pitch onto a narrow bottom packed with mill housing. Nearly 86 percent of that stock predates 1990, so whatever exterior drainage it once had is long gone. Then the saturated ground freezes and holds that moisture against the wall until spring, which is how an October storm is still in the cellar in January.
The 2005 water went through streets that look fine now. Is that still the path?
Yes. The Ashuelot has not moved. A 1961 basement on that floor is still the low opening, and a smaller October peak will use the same streets. The map of the last flood is the map of the next one.
The mill race is dry at the surface. Why would a cellar next to it still seep in October?
The channel is still there below grade. Races were cut to take the Ashuelot's power and were never filled to a dry standard, so they remain a water table against the cellars built beside them. A quiet mill leaves a wet race.
