Plain English Breakdown

The summary does not specify if future studies beyond the initial one are mandated by law and funded similarly.

State Engineer's Groundwater Study

This law requires the State Engineer to conduct a groundwater study every ten years in counties with designated control areas or where corrective controls have been ordered, and report findings.

What This Bill Does

  • Requires the State Engineer to conduct a groundwater study at least once every ten years in counties with designated groundwater control areas or where the state engineer has ordered corrective controls.
  • The study must assess the effects of corrective measures, compare aquifer recharge to water consumption from that aquifer, and evaluate future development impacts on the aquifer.
  • Allows for mapping, modeling, and drilling monitoring wells as part of the study process.
  • Requires public reporting of study results within 60 days after completion.
  • Appropriates $500,000 from the general fund to support the initial study.

Who It Names or Affects

  • The State Engineer's Office
  • Counties with designated groundwater control areas or corrective controls ordered by the state engineer

Terms To Know

Aquifer
A layer of water-bearing permeable rock, sediment, or soil that can store and transmit significant quantities of water.
Corrective controls
Measures ordered by the state engineer to address issues related to groundwater management.

Limits and Unknowns

  • The law only applies in counties with designated control areas or where corrective measures have been ordered.
  • Funding is limited and must be used for the specific purpose of conducting the study.
  • Future studies may require additional funding not covered by this act.
