Which of the following is NOT one of Arizona's Active Management Areas?

The region of Harquahala is not recognized as one of Arizona's Active Management Areas (AMAs). Active Management Areas are designated regions in Arizona established to promote conservation and efficient use of limited water resources, particularly in areas experiencing water scarcity issues.

Pinal, Prescott, and Santa Cruz are all officially designated AMAs that address the water supply challenges in their respective regions. Each AMA has specific regulations and guidelines aimed at managing groundwater use, safeguarding water resources for the future, and ensuring sustainable development within those areas.

Understanding the significance of these designations is crucial, especially in a state like Arizona, where water resource management is particularly important due to its desert climate and growing population. This distinction helps to clarify the efforts being taken to protect and manage the state’s vital water supply.
