White Oak Lake is located in Zemple, just south of Deer River. The best way to access the lake is to take Cr 139 south (CR 139 is just east of Deer River) and follow it around the 90 degree bend to the east until you reach the White Oak access road. From the access, scan for waterfowl, shorebirds, eagles, and pelicans. White Oak offers the best birding during migration.
