Investigation context

Weather + hydrology context for San Jacinto County

Composite operating context — active hazards, hydrologic features, surface-water condition, and infrastructure footprint — pulled from cached snapshots only.

Active hazard footprint
0 active alerts

No NWS-driven alerts active in the cached water-summary feed. Drought + precipitation context land once those snapshots are committed.

No sewer overflow rows in the 30-day window.

Hydrology features
8 TWDB features

GULF_COAST · CARRIZO · Neches · Sabine

4 Major Aquifers · 4 Major River Basins · 3 HUC 8 Hydrologic Units

Surface water condition
1 impaired / 3 segments

33% of cached TCEQ surface segments in this county carry at least one impairment flag.

Basin: San Jacinto River Basin, Trinity River Basin

Drinking-water exposure
36 SDWIS violations

10 public water systems with cached health-based violations since 2023-04-01. 9,079 people served by those systems.

Top PWS: PB & SC WATER SUPPLY CORPORATION (15 viol.) · Top contaminant code: 1005

Stream gauge coverage
0 active gauges

No active stream gauges in the cached water-summary feed. Hydrologic stress signal lands once gauges fold in.

USGS streamflow anomaly + drought class join in next-up.

Boil-water proxy · microbial rule
No microbial violations cached

No SDWIS rule-group 100 microbial violations cached for this county. Tier-1 boil-water-equivalent events activate this lane when they post.

Treatment stress · E2 disinfectant
No disinfectant violations cached

No cached SDWIS rule-group 200 disinfectant violations in this county. Treatment-stress signal activates as new D/DBP rule violations post.

Impaired surface segments in this county
  • Lake Livingston
    Trinity River Basin · fish consumption

Impairment is a legal-use-support classification, not a direct harm claim.

Analytics snapshot

Risk trend from committed snapshots

Uses the committed county-history artifact only. Atlas does not backfill imaginary periods; if a previous snapshot is missing, this panel says so.

Interpretation

What changed and why

San Jacinto County is currently driven most by water districts in the county explorer stack, while the committed analytics lane classifies it as high pressure + high risk.

Across the latest two committed snapshots, both the county risk score and pressure score are unchanged, so the analytical read is about persistent position rather than a new spike. The county is steady across the latest committed comparison window.

High pressure + high risk
This county sits above the current statewide median on both the pressure and risk axes in the committed scatter snapshot.
Grounding and caveats

County analytics are derived from committed SDWIS, ACS county population, surface-water-quality, and TWDB hydrology snapshots. History appends one real snapshot per run and never fabricates prior periods.

  • countyRiskScore is the statewide 0-100 normalization of summed SDWIS DWRS raw scores per county.
  • pressureScore is the statewide 0-100 normalization of impaired segment counts per 100k residents when population is available; otherwise it falls back to raw impaired segment count.
  • Rank deltas compare the newest county-history snapshot against the immediately preceding real snapshot.
  • Both axes are normalized to a 0-100 statewide range for stable chart consumption.

County ↔ operator navigation

Move from county stress to named operators

County rankings show where signal concentrates. Operator pages show which named permittees and applicants are currently visible inside that signal.

The strongest visible crosslinks here come from ENTERGY TEXAS INC. Use those pages to inspect county concentration, case posture, and permit roster.
  • • County page: risk, hydrology, and statewide rank context.
  • • Operator page: county footprint, open CID case posture, and pending permit roster.
  • • Permit view: county-scoped transaction list for the current public snapshot.
