Is this a good location to see the stars? Is it dark? No city lights, flood lights or street lights to block out the sky at night?

I believe it to be great for star gazing.

It's decent but not the best by far. Light pollution from large cities create a glow that extends nearly 100 miles from its outskirts. Small towns create similar flows but normally extend 10-20 miles. In addition ranches, highways nearby create light pollution as well. The best places to view the stars are further out west in the mountain states. Which are much less densely populated and far fewer lights to pollute the sky. I've seen the night time sky out west and at Colorado bend and there's no comparison. There's thousands more stars you can see out west.

Yes

I personally star-gazed here and it is very good! It is a primitive park with grass burrs and wildlife. Be prepared for primitive conditions and a narrow, bumpy ride in with many loose cattle. A great adventure. I know no one will believe me, but the stars cast a dim shadow on my pillow. When the moon rises, it is like Tom Hanks' moon prayer in Joe vs. the Volcano movie. Large armadillos come crashing through the underbrush all night but they're interesting to watch and harmless. Bring a regular flashlight plus a dim red one for star gazing.

Camped there specifically for stargazing. It was phenomenal. They used to have a stargazer viewing area but now it's closed, gated, and used for storage! No matter. Used one of the daytime scenic view locations. Excellent stargazing outside your tent if you primitive camp on the river, too. Bring binoculars.

Yes we drove to the top and at night was great to see the stars

Yes there is plenty of spaces to star gaze I recommend hiking to the upper falls if you do their is no lights and you can see plenty of stars while enjoying the water.

Great place for stat gazing. I believe there are a few "street lights" near the ranger station/ common camping area. However it doesnt take much to get away from it and they aren't real bright to create a lot of light pollution.

Yes, there are not many lights out there.

Yes, lots of stars but if you plan on camping, it books up months in advance.
