about the only fishing that I know about is the little pond up in Cold Creek. It is nothing worth talking about though.
Camping this year is going to be rough if you want established sites. This year is going to be a huge construction year up on the mountain and only two campgrounds will be left open. Humboldt-Toiyabe National Forest - Offices
It is so bad that the ski resort is going to be letting people camp in their parking lot... for a fee of course.
If you like primitive camping, a little harder to convince the wife. You have some good options that are still up at enough altitude to beat the heat. Macks canyon group camp ground, Wheelers Pass camp ground, and of course all of the smaller places right off of the many trails. I will probably get shot for this, but check out Carpenters Canyon. There is enough room for a few tents at the end of the trail and there is a small creek. Nothing big enough for fish or anything though.
