Drought Management Plan

What is drought?

Drought happens when there is not enough water in our streams and reservoirs due to low precipitation. Reduced water supplies cause lower storage levels, so there is less water for Westminster residents, businesses, and agriculture.

What is the purpose of a Drought Management Plan? 

To ensure water supplies are available for our customer’s most critical needs, water providers must anticipate and plan for drought. Westminster City Council approved an updated Drought Management Plan in April 2019. 

What is our drought history? 

Drought is a common natural occurrence in western states like Colorado, which significantly reduces water supplies for cities, farms and rivers. Colorado is arid, receiving less than a fourth of the precipitation compared to a tropical, coastal city like Miami. By using our water more wisely and carefully all the time, but especially during drought, we can help make our water supply last through severe droughts. 

Stay up to date with statewide drought conditions with the Drought Monitor. Keep in mind these are current climactic conditions, and do not necessarily equate to utility-specific drought declarations. However, it’s a useful tool for viewing the current drought situation regionally. 

The most recent severe drought in which Westminster and much of the Denver-Metro area enacted drought restrictions was in 2002.
