Geography

The South Fork Solomon River rises in Sherman County, Kansas, and flows eastward through Thomas and Sheridan counties into Graham County. The South Fork Solomon River travels across Graham County roughly following the course of Highway 24. The South Fork Solomon River enters Graham County about ½ mile (0.8 km) south of Studley and exits Graham County about 5 mi southwest of Nicodemus. The river runs through Bogue, Hill City, Penokee, Morland and Studley, and is impounded eight miles west of Stockton, Kansas in Rooks County to form the large Webster Reservoir. The river then joins the North Fork Solomon River at Waconda Lake in northwestern Mitchell County, forming the Solomon River.
