Day 1- Self explanatory, no worries.
Day 2- For Half Dome, bypass LYV and camp up by Sunrise Creek just above the HD spur. Get an early start to beat the heat and crowds. Bears!
Day 3- As mentioned in another thread, that's a lot of ambitious climbing for one day. You getting to Sunrise Lakes is going to be questionable. CR is at 9926, there may be snow there and on the Forsyth Trail over to Sunrise. There should be a spring on the way up to CR, but essentially treat it as a dry climb for practical purposes. Better yet, either go back down to Sunrise Creek and resign yourselves to another night there, getting an early start to CR, or keep your packs with you up to the the base of the cables and take off cross country toward Quarter Domes. You'll likely have water and sites in the vicinity, and certainly less distance and elevation to re-climb, but you can also go over the CR summit, then after you get out of the brush and hit the flats on the north side, turn left and look for good sites in the trees along the rim of the canyon. Nice! If you're out or short of water, hike about a mile and a half toward Sunrise Lakes to the creek to reload. Next good camping is the backside of the trailside tarn further along the trail. Go past that and you might as well head over to lower Sunrise Lake for the night. Bears!
Day 4- At the base of the Sunrise Trail (Tenaya Lake/Creek) you're going to have a really wide ford. Right now it could be 100 yds wide and who knows how deep? Knee-deep, waist...??? You will get wet, but the water isn't moving fast, so in spite of needing to stand there in awe for a few minutes (or until you get tired of the mosquitoes eating you alive), you should be fine. You aren't going to actually "cross the road", you're going to walk down it to the Murphy Creek Trail. Murphy Creek is going to have a lot of standing water on and around the trail. You WILL get wet. You're also going to have a couple crossings: one lower down across slabs that might be kind of sketchy, but usually wide enough to spread the flow out, and then one more that will be sketchy because the channel is narrower up closer to the top. On the second, you'll want to scout downstream for a better and safer crossing than at the trail. As for Polly Dome Lakes...absolutely swampy and mosquito infested beyond comprehension. If you're not already, get used to it.
Day 5- Okay, so now you're going to go up a little and hit the May Lake Trail. I was there that time last year (no comparison to this year...not even close) and we were postholing it through snow drifts all the way up to the ascent over to the pass to Raisin Lake. Lots of mud and runoff where there wasn't snow, not to mention snow bridges that dropped us to our waists more than a few times. The mosquitoes were especially vicious in this area as well. Raisin Lake also was pretty bad. Beyond that, we had one good creek crossing in the valley there and a few smaller one that you'll be able to pretty much just step over, and, more mosquitoes. The trail up and over to May Lake may also still be at least partially obscured by snow, so follow tracks or keep an eye out for what looks the most logical. If you do lose the trail, try to pick up a view and dead reckon Mt Hoffman, because May Lake is at it's base. If for some reason you don't think you can get to the next area for camping, based on your map and estimations of the next camping, the backpacker's camp just beyond the HSC is a good place to stop...better than some of the alternatives below on the way down to/but above Snow Creek. (See warning below)
I'll separate this part because it deals with May Lake to Snow Creek You might want to go ahead and walk the road down to Hwy 120 and cross to pick the trail back up on the other side. The road down is paved, but there are probably spots where the drainage across it is going to be fairly deep. No big deal, really. The road is likely easier than the trail because of some snow, but if you do take it instead of the trail, when you hit Tioga Rd, you need to turn LEFT, walk the shoulder a few hundred yards, then cross in the big turnout where you should see some bear lockers. If you do walk the road, whatever you do, DO NOT cross directly over there or you'll be bushwhacking uphill to pick the trail back up again. If you hike down on the trail, you simply cross the road at the same turnout wit hthe lockers and keep going. Whichever way you go, once you do cross, you'll go through a series of conditions ranging from flats to steep downhills with a few small crossings and lots of muck in places.
!!!WARNING!!! As of right now, there are camping restriction at Snow Creek because of bear activity:
https://www.nps.gov/yose/learn/management/closures.htmYou'll either need to camp above it or go up toward Porcupine Creek and head out toward North Dome. It sucks, I know, because Snow Creek is an incredible place to camp, but it is what it is.
Day 6- On the way to North Dome you'll cross on creek that shouldn't be too bad. Get your water for camp here. From there you can scrounge around for campsites up in the rocks above the dome or around the spur to Indian Rock, or you can drop into the saddle on the spur to North Dome itself and find a few sites down there.
Day 7- I'm going to assume you're not planning to backtrack, so you'll come out downhill of North Dome. From here to the top of Yosemite Falls you'll have a a few crossings: Royal Arch, Lehamite, and Indian Canyon Creeks. They're generally narrow, but reports are saying they're running fast. Make do.
At the top of Yosemite Falls, load up on water. Stay safe and realize where you are and get it in a safe place upstream. The Falls Trail is a bitch to descend Cobbles from hell at the top, hot, switchbacks make it seem much longer than it is. Keep that in mind.
This might come in handy for a basic overview, eve nthough it's now slightly outdated:
