I notice our springs have been a little slow all year, but then we didn't have much of a winter last year, (in terms of water).
I wouldn't worry too much, unless we have another dry winter in G.C.
These old springs have mostly been running for centuries, and they will most likely keep on running too.
Years ago, I remember seeing your pond dry up, but it was in a time where we had two or three years in a row like this year. So don't be surprised if it happens. It's just a good time to clean out the pond.
