Water Restrictions

Living in the semi-arid climate of Colorado means you’ve probably experienced water restrictions. Mandatory water restrictions are typically due to drought cycles. By conserving water year-round and using water wisely, you can help sustain our water supply –– reducing the risk of mandatory restrictions and ensuring more water fun year-round. If you’re a Thornton resident, you’ll be notified if there’s any change in the restriction level, but it’s just easier to conserve regularly.

Drought Status

Water supply conditions and current demand patterns indicate that Thornton’s July 1, 2019 reservoir storage may be at approximately 75 percent of capacity, which is below normal. Stage 1 Drought Watch has been declared with the goal of reducing overall demand by 10 percent until reservoirs return to target levels. Check out the tips for water-wise lawn care and learn more about how you can help Thornton keep a healthy water supply on our Tips and Resources Page.

Top Three Drought Watch Voluntary Standards:

  • 1.

    Limit established turf irrigation to the early morning or late evening hours to reduce water lost to evaporation.

  • 2.

    Limit established turf irrigation to no more than 2 days per week, selected at the customer’s discretion. Irrigation at most Thornton parks is being reduced by 50 percent while sports turf will be watered as needed.

  • 3.

    No turf irrigation between October 15, 2018 and April 1, 2019.
