High pressure + high risk
Interpretation
What changed and why
Smith County is currently driven most by county returns 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.

Operator lane
Operators visible in this county snapshot
Ranked only from the current permittee and CID applicant snapshot. Atlas links out where operator presence is visible; it does not invent a deeper hierarchy or historical market share.
0 visible operators
No operator grouping is visible for this county in the current permit and CID snapshot.
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.
This county currently has no grounded operator crosslink from the permit/CID dataset, so Atlas keeps the page anchored in county and permit context only.
- • 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.
