Question: What is the highest point in the state where Clendening Lake is located?

full_context: Document 1: Clendening Lake: Clendening Lake is a reservoir located in Harrison County, Ohio, in the United States, formed by damming Brushy Fork, East of Tippecanoe.
Document 2: Seattle: The city itself is hilly, though not uniformly so. Like Rome, the city is said to lie on seven hills; the lists vary, but typically include Capitol Hill, First Hill, West Seattle, Beacon Hill, Queen Anne, Magnolia, and the former Denny Hill. The Wallingford, Mount Baker, and Crown Hill neighborhoods are technically located on hills as well. Many of the hilliest areas are near the city center, with Capitol Hill, First Hill, and Beacon Hill collectively constituting something of a ridge along an isthmus between Elliott Bay and Lake Washington. The break in the ridge between First Hill and Beacon Hill is man-made, the result of two of the many regrading projects that reshaped the topography of the city center. The topography of the city center was also changed by the construction of a seawall and the artificial Harbor Island (completed 1909) at the mouth of the city's industrial Duwamish Waterway, the terminus of the Green River. The highest point within city limits is at High Point in West Seattle, which is roughly located near 35th Ave SW and SW Myrtle St. Other notable hills include Crown Hill, View Ridge/Wedgwood/Bryant, Maple Leaf, Phinney Ridge, Mt. Baker Ridge and Highlands/Carkeek/Bitterlake.
Document 3: Conotton Creek: Conotton Creek ( ) is a tributary of the Tuscarawas River, 38.7 miles (62.3 km) long, in eastern Ohio in the United States. Via the Tuscarawas, Muskingum and Ohio Rivers, it is part of the watershed of the Mississippi River, draining an area of 286 square miles (741 km²) in Carroll, Harrison and Tuscarawas County, Ohio. The source is at 1240 feet and the mouth is at 874 feet. Dover Dam, downstream on the Tuscarawas river, is normally dry, but can impound a reservoir on Conotton and tributaries to a pool elevation of 916 feet for downstream flood control by the Corp of Engineers. From its source in eastern Harrison County, Ohio the creek flows west northwest through Jewitt, Scio, Conotton, Bowerston, Leesville, Sherrodsville, New Cumberland and Somerdale before reaching its mouth in central Tuscarawas County, Ohio. The Wheeling and Lake Erie Railway is situated in the valley. Ohio State Route 151 runs in the valley from near the source to Bowerston. Ohio State Route 212 run along the valley from Bowerston to the mouth. The Conotton Creek Trail runs from Bowerston to Jewett.
Document 4: Boston: Boston has an area of 89.6 square miles (232.1 km2)—48.4 square miles (125.4 km2) (54.0%) of land and 41.2 square miles (106.7 km2) (46.0%) of water. The city's official elevation, as measured at Logan International Airport, is 19 ft (5.8 m) above sea level. The highest point in Boston is Bellevue Hill at 330 feet (100 m) above sea level, and the lowest point is at sea level. Situated onshore of the Atlantic Ocean, Boston is the only state capital in the contiguous United States with an oceanic coastline.
Document 5: Hocking Hills: The Hocking Hills is a deeply dissected area of the Allegheny Plateau in Ohio, primarily in Hocking County, that features cliffs, gorges, rock shelters, and waterfalls. The relatively extreme topography in this area is due to the Blackhand Sandstone (so named because of Native American graphics on the formation near Newark, Ohio), a particular formation that is thick, hard and weather-resistant, and so forms high cliffs and narrow, deep gorges.
Document 6: Chickamauga Lake: Chickamauga Lake is a reservoir in the United States along the Tennessee River created when the Chickamauga Dam, as part of the Tennessee Valley Authority, was completed in 1940. The lake stretches from Watts Bar Dam at mile 529.9 (853 km) to Chickamauga Dam at mile 471.0 (758 km) making the lake 58.9 miles (94.8 km) long. It borders Rhea County, Meigs County, and Hamilton County with 810 miles (1,303 km) of shoreline and two bridges crossing it at State Highway 60 and Highway 30. The lake is commonly used for recreational and outdoor activities, especially at the southern end, due to the high population density surrounding it. It was named after the Chickamauga (tribe) of Cherokees who used to live in the area.
Document 7: Tennessee: The highest point in the state is Clingmans Dome at 6,643 feet (2,025 m). Clingmans Dome, which lies on Tennessee's eastern border, is the highest point on the Appalachian Trail, and is the third highest peak in the United States east of the Mississippi River. The state line between Tennessee and North Carolina crosses the summit.

Document 9: Oklahoma: Oklahoma has four primary mountain ranges: the Ouachita Mountains, the Arbuckle Mountains, the Wichita Mountains, and the Ozark Mountains. Contained within the U.S. Interior Highlands region, the Ozark and Ouachita Mountains mark the only major mountainous region between the Rocky Mountains and the Appalachians. A portion of the Flint Hills stretches into north-central Oklahoma, and near the state's eastern border, Cavanal Hill is regarded by the Oklahoma Tourism & Recreation Department as the world's tallest hill; at 1,999 feet (609 m), it fails their definition of a mountain by one foot.
Document 10: Portland, Oregon: Though much of downtown Portland is relatively flat, the foothills of the Tualatin Mountains, more commonly referred to locally as the ``West Hills '', pierce through the northwest and southwest reaches of the city. Council Crest Park, commonly thought of as the highest point within city limits, is in the West Hills and rises to an elevation of 1,073 feet (327 m) The city's actual high point is a little - known and infrequently accessed point (1,180 feet) near Forest Park. The highest point east of the river is Mt. Tabor, an extinct volcanic cinder cone, which rises to 636 feet (194 m). Nearby Powell Butte and Rocky Butte rise to 614 feet (187 m) and 612 feet (187 m), respectively.

Document 14: Huntington State Park: Huntington Reservoir was completed in 1966 by the United States Bureau of Reclamation as part of an Emery County irrigation and recreation project. This warm-water reservoir supports waterskiing, fishing, and crawdad catching. Largemouth bass and bluegill are the most noteworthy fish in this warm-water lake. Many migratory birds, specifically waterfowl, are sighted in this area.
Document 15: Campbell Hill (Ohio): Campbell Hill is, at 1,550 feet (470 m), the highest point in elevation in the U.S. state of Ohio. Campbell Hill is located within the city of Bellefontaine, 2 miles (3.2 km) northeast of downtown.
