Those look good except for the county Park one. You're a bit west of where you want to be. Here is a link to Yahoo Maps that shows the park.

If linky no worky, you can find it in Yahoo Maps bt looking up the intersection of Park Drive and St Francis in Lakeport



On Edit:
Looking at your State Park map, find Park Drive toward the upper left of your map. Continue north on Park Drive, and you will run right off a ramp into the lake as you enter the county Park.
