Since the nominal lake level above stream bed is 28 meters, this seems to match my experience. Yes, the lake is a reservoir. I could probably upload the csv file if you want to take a look.
Bingo.
Thanks
Seems the TCX itself would be fine. There are lots of programs that can be used to view those (gpxsee is one I like). Your situation might be explained enough not to really look at it any further.
