New Rockford Canal

New Rockford

The New Rockford Canal is part of the Garrison Diversion Unit Principal Supply Works.  The canal begins on the east side of the Lonetree Wildlife Management Area, in central North Dakota and runs through Wells and Eddy counties. 

Length: 41.5 miles
Construction: 1983 - 1991

Who takes care of it?
Under a cooperative agreement with the Bureau of Reclamation, the Garrison Diversion Operations & Maintenance (O&M) staff provides the routine maintenance to the canal, including:

  • monitoring and inspection
  • building and equipment maintenance
  • rock and gravel hauling
  • spraying for noxious weeds

Lonetree Wildlife Management Area
Under the original Garrison Diversion Unit plan, the Lonetree Reservoir was intended to be a regulating reservoir connecting the McClusky Canal and the New Rockford Canal.  The water management reservoir was deauthorized by the Dakota Water Resources Act of 2000 and, instead, developed into a wildlife conservation area.  The Lonetree Wildlife Management Area is operated by the North Dakota Game and Fish Department.
