What type of water is classified as other surface water in Arizona?

The classification of "other surface water" in Arizona typically includes water that is not categorized as groundwater or directly as surface water from more traditional sources. Water from lakes and rivers fits this classification because it comprises the natural surface water bodies that are essential to Arizona's water sources. These bodies of water play a crucial role in the state's ecosystem and water management framework.

Rainwater is generally categorized separately under precipitation and not under the "other surface water," while effluent pertains to treated wastewater, which serves a different regulatory and use purpose. Desalinated water, processed to remove salt from seawater, is also not included under this classification since it is derived from an entirely different source and methodology. Therefore, water from lakes and rivers is distinctly recognized as a key component of Arizona's hydrology and is accurately referred to as other surface water in the context of this question.
