When you unfold the brochure or walk in permit that you are supposed to have anytime you access the refuge there is a map with all the roads and lakes and yes there are a lot more lakes north and south unit. If you don't have a brochure go to this website White River National Wildlife Refuge and download the brochure map. It is worth a daytrip to find all the lakes and gate locations. Also be careful about being on the refuge without this brochure, it states that anytime you are on refuge property this must be on your person. There are brochure boxes at each entrance north unit off of HWY. 1 and south unit at Ethel AR., you can usually get them at surrounding baitshops and stores.
