I also hiked in 2001. We hiked June 17 - June 24. My party hiked only the section from Toulumne Meadows to Sonora Pass and then on down one more day on a tributary trail.
Just to clarify, the Tahoe Yosemite Trail and the PCT are the same for 99% of the route.
There weren’t any bad water crossings that year, had to get the feet wet a couple of times, but nothing we couldn’t handle. Can’t remember any built bridges except the one just out of tuolumne meadows at Glen Aulin.
I wouldn’t worry about the river crossings on that section this year. It looks like things are going to be melting early. Check out the following link for real time data on sierra snow melt.

Also if you want a tip for a slightly off PCT section of trail that gives you some awesome scenary after days of bug infested forests look at the following route. At least check out the following on your maps: After hiking East through Grace Meadows, before you reach Dorothy Lake, take the trail North to Bond Pass. From Bond Pass follow the old jeep trail along the crest to where it meets up with the PCT again. The route passes High Emigrant Lake and passes over peak 10,825. This route is excelent! It gets you up out of the forest and has expansive views to the west and east. The PCT section you miss is similar to what you have already experienced from Tuolumne Meadows to this point. Getting up high was the pinacle of our trip!
Check out the map link of the deviated route. You also can follow the trail north on the map by clicking on the map.
