Environmental intelligence domain
A Governed Intelligence Model of the Great Salt Lake.
The Great Salt Lake domain connects historical observations, lake elevation records, geography, hydrology, source evidence, trends, models, uncertainty, and conditional scenarios without collapsing them into one undifferentiated answer.
Observed environmental evidence remains connected to its source, date, method, location, and governing classification.
The lake is not one number.
The domain preserves source location, measurement method, observation date, revision history, north-arm versus south-arm distinctions, inflow, snowpack, precipitation, evaporation, depletion, and uncertainty.
- Historical Observation
- Event or Measurement
- Current Governed State
- Revision or New Evidence
Every environmental claim retains its evidence class.
Observed
Directly reported or measured by an identified source.
Required evidence: named source, method, and applicable date or assumption.Must not become: A modeled, forecast, or scenario result.Derived
Calculated from governed observations through a disclosed method.
Required evidence: named source, method, and applicable date or assumption.Must not become: A direct source observation.Modeled
Produced by a named model with recorded inputs and version.
Required evidence: named source, method, and applicable date or assumption.Must not become: A measured fact.Forecast
A time-bound future estimate from an identified source or model.
Required evidence: named source, method, and applicable date or assumption.Must not become: A guarantee.Scenario
A conditional result based on explicit assumptions.
Required evidence: named source, method, and applicable date or assumption.Must not become: A forecast or operating recommendation.Unavailable
The necessary source or observation is absent, unsupported, or not yet governed.
Required evidence: named source, method, and applicable date or assumption.Must not become: An apparent zero or inferred fact.Trends remain connected to their window, method, and evidence.
Historical markers
1847–Present governed record. Previous record low: 4,191.35 ft in 1963. Historical high: 4,211.6 ft in 1986. Record low: 4,188.5 ft in 2022.
Observed · Dated snapshotMulti-window analysis
30-day movement: 0.0 ft. 10-year change: −0.45 ft. Since the 1963 low: +1.55 ft. Full history since 1847: −6.3 ft.
Derived · April 30, 2025Known evidence gaps
Inflow, snowpack, precipitation, evaporation, and depletion remain excluded from the displayed comparison until governed records are available.
UnavailableRepresent the lake as connected state, not a static chart.
Lake regions, observation stations, tributaries, inflows, water level, salinity where supported, snowpack, precipitation, evaporation, diversions, infrastructure, institutions, events, and scenarios are represented as governed relationships.
This is an expanding environmental intelligence domain, not a completed model of the entire Great Salt Lake system.
