Aquifer Land Surface Change Explorer

This interactive map illustrates how the depth to the water table—measured from the Land Surface Datum (LSD)—has changed over time at the aquifer and county level. The LSD is the fixed height of the land surface at a well site, measured in feet.

 

  • A positive value indicates the depth to water has increased (the water table has dropped), signaling a reduction in groundwater availability.

  • A negative value indicates the depth to water has decreased (the water table has risen), signaling a recovery or increase in groundwater availability.

User Guidance

  • Select a Date Range
    • Enter the start date in the field labeled B_Start_Date.
    • Enter the end date in the field labeled B_End_Date.
    • Dates must be formatted as YYYYMMDD (Year, Month, Day).
  • Example
    • Start Date: 20200101 (January 1, 2020)
    • End Date: 20231231 (December 31, 2023)
  • Interpret the Results
    • Positive number = The land surface dropped (subsidence), often linked to heavy groundwater withdrawal.
    • Negative number = The land surface rose slightly (rare).

Texas County Well & Aquifer Explorer

This interactive map provides a detailed view of Texas water resources at the county level. Users can explore total wells, associated aquifers, well types, and depth metrics (maximum and average). It’s designed to help businesses, researchers, and policymakers understand water availability and aquifer relationships across the state.

 

 

User Guidance

 

  • Hover over a county to see aquifers and well depth stats.
  • Use filters to view specific well types or depth ranges for both county and aquifer.
  • Click on a county for a detailed breakdown of aquifers and well metrics.

 

Use Cases

  • Water Resource Planning: Identify areas with high well density or deep wells.
  • Business Decisions:  View specific well types or depth ranges for both county and aquifer.
  • Academic Research: Analyze aquifer distribution and well characteristics.

 

Notes:

Texas has over 160,000 wells that publish data. This map shows county-level summaries for faster performance. For a map with all known water wells in Texas contact us at txwaterintel@proton.me
