Humboldt Capture Query Tool (Provisional)

January 30, 2026

The HCQT provides easy access to model-estimated capture and storage change data, supporting informed decisions about integrated water resource management. The HCQT displays 100 years of estimated groundwater pumping impacts, based on groundwater models for the upper, middle, and lower Humboldt River Basin.

Key Features

  • Comprehensive Capture Components
    Explore sources of water for capture, such as:
    • Stream Capture – Reduction in streamflow caused by groundwater pumping.
    • Groundwater Evapotranspiration Capture (ETg) – Reduction in groundwater evapotranspiration due to groundwater pumping.
    • Storage Change – Changes in groundwater storage due to groundwater pumping, the first source of water to a well.
    • Drain Capture – Reduced agricultural drain flow due to groundwater pumping in the lower Humboldt River Basin.
  • Custom Plots
    Generate estimated capture and storage change curves for selected pumping locations and depths.
  • Integrated Data
    Access results from potential capture analyses for the Humboldt River Basin from the supporting model application and capture results provisional data releases.

Groundwater pumping can significantly impact streamflow and other water resources. HCQT provides a clear, science-based way to visualize these interactions and support informed water management decisions across the Humboldt River Basin.
