Weather context for Texas water risk.
The headline live layer here is the TCEQ surface-water-quality assessment (cached statewide). Active hazard alerts, drought class, precipitation totals, and temperature anomalies are wired into the data lib but not yet committed as cached snapshots — they are listed below as planned signals so demo viewers can see the roadmap.
Surface water condition by county
Cached TCEQ surface water quality assessment shown as the seed weather-context layer until the planned NWS, drought, precipitation, and temperature snapshots land.

- •Flip between metric modes to see which counties stay bright across unrelated burdens versus which only flare in one layer.
- •Use overlays to isolate counties where the highlighted pattern may explain why a metric spikes or refuses to move.
- •Check the top list for repeat names, then trace whether they cluster geographically or break the regional pattern.
Impairment status is a legal-use-support classification, not a direct harm claim. Counties with zero rows have no classified surface segments in this snapshot — not necessarily zero water condition concerns.
- NWS active alertsFlood, flash flood, severe storm, heat — counted per county and color-banded.
