Big Sugar Creek is a waterway of 40-50 miles in length in the Ozark Mountains of southwest Missouri. Big Sugar starts near the Arkansas state line. Only about 24 miles (39 km) of this is floatable during the spring and summer. The gradient is near 9 from Highway 90 to Cyclone and 6 to Pineville, Missouri. Big Sugar starts from three tributaries. One flows north from Garfield, Arkansas, and one, west near Seligman, Missouri, and another, south from Washburn, Missouri. Big Sugar flows west down Sugar Creek Valley, where it is joined by Otter Creek, from Pea Ridge, Arkansas. Flowing north for two or three miles (5 km), Big Sugar is joined by White Oak. Flowing north for four more miles is Brush Creek. Next is the community of Mountain. From Mountain, Big Sugar flows west for two miles (3 km) where Pine Creek joins.
