On June 21, 2021. (today) water was flowing good at the source near Halfway Camp on the Vivian Creek Trail. Before you head up the little hill to the juntion to Halfway Camp the creek is dry where it crosses the trail but it is flowing upstream. Just follow the creek drainage less than 1/2 mile upstream. Plenty of flow to fill bottles. Approximate location of flowing water: https://caltopo.com/m/P749
As always water is flowing right along the trail at Vivian and High Creek Camps.
