Phase 3 of the Government Highline Canal Rehabilitation project begins November 1, 2020.
It is anticipated that Phase 3 will be completed no later than April 1, 2023.

Goals of this continuing project are to:

  • Reduce Colorado River salinity
  • Control seepage
  • Increase canal capacity

Construction Zones for Phase 3

The primary construction zone is from 36 3/10 Road to 35 3/10 Road.
Construction-related activity will also take place on the canal service roads from approximately 1/2 mile east of Elberta Avenue to 35 3/10 Road, and public roads in the area.

Construction Activity
Work may be ongoing seven days a week, up to 12 hours a day, given the demands of completing each annual component of this project while water is out of the canal.

Thank you very much for your understanding and cooperation.

GVWUA Irrigation Season

Irrigation season runs from April through October.

Mid-October is usually when we start emptying our canals.

Dates are subject to change depending on weather conditions or other unforeseeable events.


GVWUA is responsible for the flow of water in its canal, in its laterals and through its headgates.

All parts of delivery systems (ditches, laterals, pipelines, pumps) beyond the headgates are the responsibility of landowners.

If subdivisions in the GVWUA service area are interested in organizing their own laterals via a Homeowners' Association, please send an email to
