It's still open mid-October 2022 with no water service.

Campsites are listed on Recreation.gov as available on the first come basis. https://www.recreation.gov/camping/campgrounds/231912

We stayed there last September. Mid Sept., I believe. Nothing locked, bathrooms and water were open. We'd often thought of driving up and camping there in our yearly fall trips out west but had never gotten around to it. We will be back! Great place.

Call the ranger station in Pinedale to find out.
