Return, Spiller, Matterhorn Creeks - Water Availability

[Anish]

Hello All,

I have a rare chance this summer to make an extended backpack trip, and I have my eye on Northern Yosemite as I've never been to that region. My ideal route has me spending a night each in the meadows at the heads of each of these three canyons.

I normally plan to camp near lakes, thus water is never a question. But considering none of my desired campsites have lakes, I would be reliant upon the 3 creeks. Considering this is looking to be a dry year, can I expect to find water flowing around the 3 respective canyon heads? I'm not sure if these are seasonal or year round creeks, so I would appreciate any insights. I will be there last week of August.

If water will be a problem, I will have to re-route. I've made arrangements for a shuttle between Virginia Lakes and Twin Lakes so I can make a scenic point to point. I am super excited about it, but need to resolve the water question before finalizing.

Thanks for any input!

Have not been up Spiller,but Matterhorn won't go dry. And return has a lake near the upper end, with campsites...

Should be a great trip....
