Yes
The Narrows opened very late this year at the start of July because of the excessive snowfall/rainfall. To hike up from the bottom the river can't exceed 140 cubic feet/second. To do the top down hike it can't exceed 120 cubic feet/second.
No hight water
Water is freezing. If you're planning on hiking much of the river I'd recommend renting the dry suits you can get in town from an outfitter.
