Located in the
Northwest Region of the state, in the
Solomon River Drainage Basin. Stretching from the high plains of western Kansas, from which the Solomon River gets its start, the Solomon Valley slopes gently down as the river flows east along Highway 24. The river is about 300 miles long. Once also known as the Nepaholla river, is formed by its two branchesthe N and S both of which rise in
Thomas County, within 10 Mi. of each other, and for the first 10 Mi. flow almost parallel to each other at a distance of not over 4 or 5 Mi. The N branch flows in a NE direction through
Thomas County, the NW corner of
Sheridan County, the extreme SW corner of
Decatur County, the S portion of
Norton County and
Phillips County, the SW corner of
Smith County and the NE corner of
Osborne County and into
Mitchell County. The S fork flows almost due E through
Thomas County,
Sheridan County,
Graham County,
Rooks County and
Osborne County and unites with the other branch about 2 Mi. East of the West line of
Mitchell County.
