If we can't use the positions directly, i should have enough photos of the river to roughly determine coordinates and will upload to a flickr album when home next week. Have already visually verified the light sequence of the piles upriver from the barage, and will try and get some more of the tidal section before I leave Goolwa tomorrow

Quick drive past on that one, and regular drive past on the Snug change - haven't done any of the older ones.
