Is the sidewalk lit at night? If so, how well, and along the lake?

Very well lit

Yes it's lit up.

There are actually 2 Dobson Ranch parks. I'm assuming you're talking about the one right on Dobson Road it has the library right next to it, correct? If so, it is lit but not very well. The police station is also right next to the park which helps a little bit. In terms of safety. But the park sidewalks really aren't lit like they should be and along the water is actually quite dark. Hope this helps good luck and God bless.

It is until the park is closed. When it's open it's lights are bright, but dark enough to enjoy the moonlight over the pond/lake.

I am unsure
