Dave Steindorf has been working to get realtime online information for the McCloud River releases from McCloud dam. PG&E finally started reporting this recently through CDEC. Dreamflows has just started reporting it.
The AW McCloud page links to this gauge, and will be displaying the info soon.
This new online gauge allows people to compare flows from dam release with flows from side streams. It is especially helpful if you can't get to Ah-Di-Nah to launch and want to know if there is sufficient flow in the river above.
