I know the locations on the great lakes.
WAAS and Differential GPS as used here in the USA are similar in function, but are different in how they get the signal to the user.
WAAS uses correction data sent out by the GOES satellites to the end users.
DGPS uses correction data sent out by more localized long wave transmitters to the end users.

I suspect you are thinking of DGPS, and not WAAS.

If what he was seeing was a DGPS station, it wouldn't look abandoned. All the ones I've been at are fairly well maintained.
