BELLE FOURCHE DAM (ORMAN DAM)
Owl Creek
East of Belle Fourche off U.S. 212
National Register 11/23/1977
Belle Fourche Dam is a principal feature of the Belle Fourche Project,
which was among the first irrigation projects constructed under the Reclamation
Act of 1902. The primary purpose of the dam is to store water for
agricultural use downstream in the general vicinity of Newell, Vale, and
Nisland, South Dakota. The dam is a massive homogeneous earth-fill structure
with a crest length of 6,262 feet. When completed in 1911, the dam
was the largest of its type in the world. In April 1989, Belle Fourche
Dam was designated a National Historic Civil Engineering Landmark.

BELLE FOURCHE DITCHRIDER'S HOUSE
½ Mile east of the town of Nisland
immediately north of US Highway 212
National Register 1/31/02
This small one-story frame cottage is one of eleven ditchriders' houses
that were constructed on the Bureau of Reclamation's Belle Fourche Project.
Built in 1916, the house is significant for its association with
ditchriders, key players in the successful operation of irrigation projects.
The primary duties of ditchriders were, and in many places still are,
to monitor the condition of canals and ditches and control the amount
of water delivered to farmers. Ditchriders houses were built at convenient
locations along canals and laterals to facilitate work within the irrigation
project.
