Section 9.286 - Upper Lake Valley(a)Name. The name of the viticultural area described in this section is "Upper Lake Valley". For purposes of part 4 of this chapter, "Upper Lake Valley" is a term of viticultural significance.(b)Approved maps. The four United States Geological Survey (USGS) 1:24,000 scale topographic maps used to determine the boundary of the Upper Lake Valley viticultural area are titled: (1) Lakeport, 1958; photorevised 1978; minor revision 1994;(3) Bartlett Mountain, 1996; and(c)Boundary. The Upper Lake Valley viticultural area is located in Lake County, California. The boundary of the Upper Lake Valley viticultural area is as described as follows: (1) The beginning point is on the Lakeport map at the intersection of Lyons Creek and the western shore of Clear Lake in Section 31, T15N/R9W. From the beginning point, proceed south in a straight line to an unnamed light-duty road known locally as Lafferty Road; then(2) Proceed west along Lafferty Road to its intersection with an unnamed secondary highway known locally as Lakeshore Boulevard; then(3) Proceed north on Lakeshore Boulevard to its intersection with an unnamed light-duty road known locally as Whalen Way; then(4) Proceed west on Whalen Way to its intersection with State Highway 29; then(5) Proceed north on State Highway 29, crossing onto the Upper Lake map, to the intersection of the highway and the southern boundary of Section 13, T15N, R10W; then(6) Proceed west along the southern boundary of Sections 13 and 14 to the intersection of the southern boundary of Section 14 with the 1,600-foot elevation contour; then(7) Proceed in a generally northwesterly direction along the meandering 1,600-foot elevation contour to its intersection with an unnamed, unimproved road in Section 17, T15N/R10W; then(8) Proceed north in a straight line, crossing Scotts Creek, to the 1,600-foot elevation contour in Section 8, T15N/R10W; then(9) Proceed northeasterly, then southeasterly along the 1,600-foot elevation contour to its intersection with an unnamed 4-wheel drive road in Section 9, T15N/R10W; then(10) Proceed northwest in a straight line to the marked 2,325-foot elevation point on Hell's Peak; then(11) Proceed southeast in a straight line to the intersection of the 1,600-foot elevation contour and the southern boundary of Section 30 along the Mendocino National Forest boundary, T16N/R9W; then(12) Proceed southeast along the meandering 1,600-foot elevation contour to its third intersection with the Mendocino National Forest boundary, along the eastern boundary of Section 31, T16N/R9W; then(13) Proceed south, then west along the Mendocino National Forest boundary to its intersection with the 1,600-foot elevation contour along the northern boundary of Section 5, T15N/R9W; then(14) Proceed southeasterly along the meandering 1,600-foot elevation contour, crossing onto the Bartlett Mountain map, to the intersection of the 1,600-foot elevation contour and the Mendocino National Forest boundary along the eastern boundary of Section 9, T15N/9RW; then(15) Proceed south, then east along the Mendocino National Forest boundary to its intersection with the 1,600-foot elevation contour along the northern boundary of Section 15, T15N/R9W; then(16) Proceed south, then northwest along the meandering 1,600-foot elevation contour, crossing onto the Upper Lake map, and continuing southeasterly along the 1,600-foot elevation contour crossing back and forth between the Bartlett Mountain map and the Upper Lake map, to the intersection of the 1,600-foot elevation contour and an unimproved 4-wheel drive road in Section 21, T15N/R9W; then(17) Continue southeast along the 1,600-foot elevation contour, crossing onto the Lucerne map, to the intersection of the 1,600-foot elevation contour and an unimproved 4-wheel drive road in Section 36, T15N/R9W; then(18) Proceed south in a straight line to the shoreline of Clear Lake; then(19) Proceed northeasterly along the shoreline of Clear Lake, crossing onto the Lakeport map, and continuing southwesterly along the shoreline, crossing Rodman Slough, to return to the beginning point.
