Question: The Cullasaja River is a short river that flows from Lake Sequoyah which is fed by Mirror Lake and other creeks and streams originating on the western side of the demarcation of two watersheds of what?

full_context: Document 1: French Broad River: The French Broad River flows 218 mi from near the town of Rosman in Transylvania County, North Carolina, into the state of Tennessee. Its confluence with the Holston River at Knoxville is the beginning of the Tennessee River. The river flows through the counties of Transylvania, Buncombe, Henderson, and Madison in North Carolina, and Cocke, Jefferson, Sevier, and Knox in Tennessee, and drains large portions of the Pisgah National Forest and the Cherokee National Forest.
Document 2: Brule Glacial Spillway State Natural Area: Brule Glacial Spillway is a Wisconsin Department of Natural Resources-designated State Natural Area that encompasses the valley of the upper reaches of the Bois Brule River. This valley was carved by the outlet of Glacial Lake Duluth, which occupied what is now the western portion of Lake Superior, during the retreat of the Superior lobe of Wisconsin glaciation. This outlet flowed southwestward through the valley, to what is now the St. Croix River. As the glacier melted, and the level of Lake Superior dropped, the direction of flow shifted to its present northeastward course, towards Lake Superior. A high point in a vast bog near Solon Springs marks the divide between the watersheds of the Gulf of Mexico and the Atlantic Ocean. This divide was used for thousands of years, by Native Americans, European explorers, fur traders, and settlers as a portage between the two watersheds.
Document 3: Mills River (North Carolina): The Mills River is located in Transylvania and Henderson counties, North Carolina, United States is a tributary of the French Broad River. The river flows out of the Pisgah Ranger District of the Pisgah National Forest in two forks: the North Fork, which drains the slopes just south of the Blue Ridge Parkway between Asheville and Mount Pisgah, and the South Fork, which drains the area of the Pisgah Ranger District just east of the Cradle of Forestry in America, including the slopes of Black Mountain. The Mills River flows into the French Broad River northwest of Hendersonville between NC 191 and Interstate 26.
Document 4: Saint Lawrence River Divide: The Saint Lawrence River Divide separates the Great Lakes Basin from the rest of the Atlantic Ocean watershed. Two canals cross the divide: The Chicago Sanitary and Ship Canal crosses the Chicago Portage and connects Lake Michigan to the Mississippi River watershed. The Erie Canal connects Lake Erie to the Hudson River watershed. Historically there were additional canals, e.g., the Ohio and Erie Canal, but most of these are no longer in operation.
Document 5: Great Divide Basin: The Great Divide Basin or Great Divide Closed Basin is an area of land in Wyoming's Red Desert (United States) where none of the water falling as rain to the ground drains into any ocean, directly or indirectly. It is therefore considered an endorheic basin, and it adjoins the Continental Divide in southern Wyoming. To the west of the basin is the Green River watershed, draining to the Gulf of California/Pacific Ocean; to the east is the North Platte watershed, draining to the Gulf of Mexico/Atlantic Ocean. The basin is very roughly rectangular in shape; the northwest corner is in the Wind River Range near South Pass, about 40 mi southwest of Lander, and the southeast corner is in the Sierra Madre Range near Bridger Pass, about 20 mi southwest of Rawlins.
Document 6: Colorado drainage basins: The U.S State of Colorado includes the headwaters of several important rivers. The state is divided into two major hydrographic regions by the Continental Divide of the Americas. East of the Continental Divide, surface waters flow via the South Platte River, the North Platte River, the Republican River, the Arkansas River, the Cimarron River, the Canadian River, or the Rio Grande to the Gulf of Mexico. West of the Continental Divide, surface waters flow via the Green River, the upper Colorado River (formerly the Grand River), or the San Juan River into the Colorado River and on to the Gulf of California. Colorado also has three significant endorheic basins: the San Luis Closed Basin in the San Luis Valley, and the Bear Creek Basin and the White Woman Basin spanning the Colorado-Kansas border north and south of the Arkansas River.
Document 7: Swannanoa River: The Swannanoa River flows through the Swannanoa Valley of western North Carolina, and is a major tributary to the French Broad River. It begins at its headwaters in Black Mountain, NC, however, it also has a major tributary near its headwaters: Flat Creek, which begins on the slopes of Mount Mitchell. The Swannanoa River ends when it meets the French Broad at Biltmore Estate in Asheville. The river is 22 miles or 35 kilometers long, and it flows entirely within the geographical boundaries of Buncombe County. It is a valuable resource to the county, providing drinking water to the Asheville metropolitan area, and numerous recreational opportunities. In September 2004, massive rains from the remnants of Hurricane Frances and Hurricane Ivan caused the Swannanoa to flood, causing major damage to the Biltmore Village section of Asheville, and to the other communities that it flows through.
Document 8: Nolichucky River: The Nolichucky River is a 115 mi river that flows through Western North Carolina and East Tennessee, in the southeastern United States. Traversing the Pisgah National Forest and the Cherokee National Forest in the Blue Ridge Mountains, the river's watershed is home to some of the highest mountains in the Appalachians, including Mount Mitchell, the highest point in the eastern United States. The river is a tributary of the French Broad River, and is impounded by Nolichucky Dam near Greeneville, Tennessee.
Document 9: Gulf of Mexico: The Gulf of Mexico (Spanish: "Golfo de México" ) is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama and Florida border the Gulf on the north, which are often referred to as the "Third Coast" in comparison with the U.S. Atlantic and Pacific coasts, or sometimes the "south coast", in juxtaposition to the Great Lakes region being the "north coast." One of the gulf's seven main areas is the Gulf of Mexico basin.
Document 10: Watauga River: The Watauga River is a large stream of western North Carolina and East Tennessee. It is 78.5 mi long with its headwaters on the slopes of Grandfather Mountain and Peak Mountain in Watauga County, North Carolina.
Document 11: Two Ocean Pass: Two Ocean Pass is a mountain pass on North America's Continental Divide, in the Teton Wilderness, which is part of Wyoming's Bridger-Teton National Forest. The pass is notable for Parting of the Waters, where one stream, North Two Ocean Creek, splits into two distributaries, Pacific Creek and Atlantic Creek, at Parting of the Waters National Natural Landmark. These two creeks ultimately flow into their respective oceans. Atlantic Creek water eventually flows into the Yellowstone River and empties into the Gulf of Mexico via the Missouri River and Mississippi River. Pacific Creek water eventually flows into the Snake River and empties into the Pacific via the Columbia River.
Document 12: Parting of the Waters: Parting of the Waters is an unusual hydrologic site at Two Ocean Pass on the Great Divide, within the Teton Wilderness area of Wyoming's Bridger-Teton National Forest. Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean. At Parting of the Waters, at , North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters more-or-less equally between its two distributaries, Pacific Creek and Atlantic Creek. From this split, Two Ocean Creek waters flow either 3488 mi to the Atlantic Ocean via Atlantic Creek and the Yellowstone, Missouri and Mississippi Rivers, or 1353 mi to the Pacific Ocean via Pacific Creek and the Snake and Columbia Rivers. In the marshy area of Two Ocean Pass adjacent to Parting of the Waters, water actually covers the Continental Divide such that a fish could swim from the Pacific Ocean to the Atlantic Ocean drainages. In fact, it is thought that this was the pass that provided the route for Yellowstone cutthroat trout to migrate from the Snake River (Pacific) to Yellowstone River (Atlantic) drainages.
Document 13: Eastern Continental Divide: The Eastern Continental Divide (ECD) or Appalachian Divide or Eastern Divide, in conjunction with other continental divides of North America, demarcates two watersheds of the Atlantic Ocean: the Gulf of Mexico watershed and the Atlantic Seaboard watershed. As can be readily seen from the first map at the right, the Gulf watershed demarcated by the Great Divide in red begins along the spine of the mountains of Central America and runs through the American Rockies where is terminates in the triple divide at Triple Divide Peak in Glacier National Park along the U.S.-Canadian border where the Laurentian Divide blocks the waters from traveling south to the Gulf of Mexico.
Document 14: Cullasaja River: The Cullasaja River is a short river located entirely in Macon County, North Carolina. It is a tributary of the Little Tennessee River (and in turn the Tennessee River, Ohio River and Mississippi River), into which it flows near the county seat of Franklin. It originates to the southeast, near Highlands, the county's only other town. It flows from Lake Sequoyah, which is fed by Mirror Lake and other creeks and streams originating on the western side of the Eastern Continental Divide, which runs through the east side of Highlands.
Document 15: Toccoa/Ocoee River: The Toccoa River and Ocoee River are the names in use for a single 93 mi river that flows northwestward through the southern Appalachian Mountains of the southeastern United States. It is a tributary of the Hiwassee River, which it joins in Polk County, Tennessee, near the town of Benton. Three power generating dams are operated along it.
