In the last 6 years misery creek has only had flowing water in once.
That was about 4 years ago.
If you want to pan on site there, think outside the box, just bring 2 or 3 20ltr drums of water and a large plastic tub so that you can re-use the water.
I have done that there plenty of times .
Its better than loading up buckets of possible pay dirt and processing it at home.
Good luck :Y:
