Sounds like this incident occurred at the Wapama Falls crossing. Earlier reports stated they were washed into the Toluome River.
"Park officials said one body was recovered soon after the men fell into the Hetch Hetchy Reservoir on Wednesday morning. Rangers continue to search for the body of the second hiker."
> They were crossing the bridge and got swept in? How the hell does that happen?
The bridge there is at the base of a cascade, and during the hot weather this season, there may be some huge water flows there. Rogue, here is your video from two weeks ago. It has been a lot hotter since then.
Here's GE on the bridge. Scale shows about 100' to the lake, a 40 to 50' drop. Recently the whole bridges was washed off it's piers, and that wasn't a big a flow as this year.
