The Grand Valley Irrigation Company canal system serves approximately 40,000 acres of the Grand Valley with irrigation water, from Palisade to Mack. Our service area encompasses the area south of the canal down to the Colorado River. Our canals are the Mainline, Highline*, Kiefer Extension, Mesa County Ditch**, and Independent Ranchmen’s Ditch.

*Not to be confused with the Government Highline Canal, operated by the Grand Valley Water Users’ Association, which lies further to the north.

**Not to be confused with the Stubb Ditch, operated by the Mesa County Irrigation District.

The website of the Grand Valley Water Users’ Association provides a useful tool to help you determine which service area your property falls under.
