I have that name in my dataset, so it didn't come from Garmin because I didn't use any proprietary data like that. I thought it might have come from the USGS GNIS (Geographic Information System), but can't find it there. Also looked at the USGS NHD (National Hydrography Dataset) and it's not there either. Not on any of the historic topo's I looked at either.
So it's a mystery! Wonder where I found it?

Maybe openstreetmap?
