City of Boulder to Continue Drought Watch Following 2026 Water Supply Evaluation

Every year by May 1, the City of Boulder evaluates its current water supply conditions to determine if a specific drought response is needed. Despite the ongoing hot and dry conditions, the city has determined that mandatory water restrictions are not necessary at this time and will remain in Drought Watch. Under Drought Watch, the city is encouraging continued voluntary reductions in water use throughout the summer. The city also has permanent rules to prevent water waste, including a new rule that restricts running sprinkler systems from 10 a.m. to 6 p.m. to water lawns.

Sustained water conservation throughout the summer can help preserve the community’s water supply if dry conditions continue into next year. Important recommended actions community members can take at this time include limiting watering of lawns to 2 times per week, watering for the weather, and saving water indoors.

Limit watering to 2 times per week

Water lawns no more than two times per week according to the schedule below. Large properties and heavily used common areas, including parks, athletic fields and schools, may need additional watering days to keep grass alive for community use.

Water for the weather

Landscapes require different amounts of water based on the weather. Typically, plants need more water during hotter periods and less during cooler or wetter times of the year. Program sprinkler systems accordingly and remember to avoid watering when it rains. Also, using water in accordance with customer water budgets can save water and money; more information may be found on the Water Budgets webpage.

Save water indoors

There are many ways to reduce your water use inside. Take a shorter shower, turn off the tap while brushing teeth and wait to run your clothes and dishwasher until full.
