Seems a year or so ago I looked at the fish mapper bathymetrics and selected rivers, and it showed where the old river channel ran thru clark canyon, but looking this week, it no longer shows the old river channel. It shows on canyon ferry. Dont know if I was imagining it, or it was a different map. Not on navionics, at least the free version.
Does anyone know of an accessible map that shows this info for clark?
Thanks
