Bill Summary · HB 24

Legislative bill overview

HB 24 requires Texas groundwater conservation districts to consider "modeled available groundwater" (MAG)—scientifically estimated sustainable groundwater levels—when issuing water permits. The bill appears designed to ensure permit decisions are based on updated hydrological data rather than potentially outdated or insufficient groundwater assessments.

Why is this important

Groundwater is critical to Texas agriculture, municipalities, and industry, particularly in regions dependent on aquifers like the Ogallala. Using current MAG data in permitting decisions could prevent over-allocation of groundwater resources and promote long-term sustainability. Conversely, stricter science-based permitting could limit water availability for existing users and economic development in water-stressed areas.

Potential points of contention

  • Economic impact on agriculture and industry: Stricter permit requirements based on MAG could reduce water allocations to farmers and businesses, affecting rural economies and food production
  • Local control versus state standards: Whether conservation districts should have discretion in applying MAG data or must follow uniform statewide requirements
  • Existing permit holders: Unclear whether the bill affects renewal of existing permits or only new applications, potentially creating disputes over established water rights
