| Abstract | TWDB GAM landing page for the High Plains Aquifer System (MODFLOW-NWT, v1.02). Direct model-archive download link not yet independently verified via a Tapis test run. |
| Temporal Coverage Start | 2015-01-01 |
| Temporal Coverage End | 2025-06-30 |
| Program Area | Groundwater |

| Caveats and Usage | Regional GAM for planning and screening; not for site-specific design. Spatial extent is an approximate bounding box derived from the union of member-county boundaries for GMAs 1, 2, 3, 6, and 7 (TACC SUBSIDE texas_counties layer) — not the precise model grid extent. Temporal coverage reflects the model's report/version dates (2015 original, 2025 extension), not a confirmed historical calibration period. |
