Reasonably close, yes. Use google maps
We were there back in October of last year and the park was really over grown. The water front sites were covered with large growth and you could not see the water. We have not been this year so not sure if they have cleared any of the over growth or not.
Yes, but reserved sites are still first come first served at there's a chance on arrival you can't get one.
There are several waterfront RV sites. Site 74 has a beautiful view of the lake, and is near the restrooms/showers.
