Drought Response

Staying more than a few drops ahead.

Because we live in a semi-arid climate, we must expect and prepare for periods of drought. The city continuously monitors water supply and balances storage levels with demand. Storage levels are affected by weather, the amount of snowpack and rainfall, stream flow levels, and other factors.

Drought Watch

As of July 10, 2024, the city of Thornton is now in “Drought Watch” due to drought conditions predicted to persist in the Front Range. Thornton’s reservoir storage is normal for this time of year, however hot and dry conditions have resulted in customers using significantly more water than last year. There are no additional mandatory watering restrictions associated with Drought Watch. Customers are encouraged to be efficient with their water usage and adhere to the city’s Outdoor Water Use Rules, which require customers to irrigate turf and lawn areas no more than 3 days/week and only between the hours of 6 p.m. and 10 a.m. Learn more about how to be water-wise on our Saving Outdoors page.

Five multicolored water drops denote "no drought response", "drought watch", "stage 1, moderate to severe", "stage 2, extreme" and "stage 3, exceptional." Drought watch is highlighted.

Thornton’s Drought Management Plan:
Securing our water now, and for years to come

Thornton’s Drought Management Plan provides action-based guidance to respond to drought in ways that equal the severity of conditions. During droughts, Thornton can experience a water shortage that could require the community to reduce its water use. The plan also includes additional steps for reducing water demand and acquiring additional water supplies. Read the Drought Management Plan.

Water Use Rules and Watering Guide:
