For purposes of part 4 of this chapter, "Long Valley-Lake County" is a term of viticultural significance.(b)Approved maps. The three United States Geological Survey (USGS) 1:24,000 scale topographic maps used to determine the boundary of the Long Valley-Lake County viticultural area are titled: (1) Clearlake Oaks, California, 1996;(2) Benmore Canyon, California, 1996; and(3) Lower Lake, California, 1993.(c)Boundary.
