What it is Derived, awaiting review
This meta-model describes surface and subsurface water as physical objects and as regimes: rivers, lakes, seas, wetlands and aquifers, the catchments that feed them, the flows and levels they carry through the year, and the measured quality of the water itself.
Note: First sentence of the legacy card introduction.
Why it exists Filled
Rivers, lakes, seas, aquifers and their regimes
Distinguishing features Derived, awaiting review
- It is its own model because a water body is a connected, moving system whose identity survives changes of level and course, and because the network topology of upstream and downstream relations is the basis for almost every other water question.

Owners Filled
Steward
An ecology commons steward keeps the hydrological register: it delineates bodies and catchments, operates or accredits monitoring, and publishes regimes and status classifications, without holding any claim over the water itself.

Capabilities and actions required Derived, awaiting review
- gaugeReadingRecorded: a station reported a level, discharge or groundwater value for a moment in time
- floodStageExceeded: an observed level crossed a defined threshold at a station
- lowFlowThresholdCrossed: flow fell below a stated low-flow reference for a reach
- waterBodyDelineationRevised: the geometry or identity of a body or catchment was redrawn after new evidence

Standards and interfaces required Derived, awaiting review
- hydrometricFeedContract: terms for real-time or near-real-time delivery of station readings, including latency, quality flags and outage notice
- qualityLaboratoryExchangeContract: terms for laboratories submitting analyses, covering method declaration, detection limits and re-analysis
- transboundaryBasinExchange: terms for exchanging flow and quality data with a neighbouring register for a shared basin
- abstractionReturnDisclosure: terms under which operators report abstracted and returned volumes at agreed grain
- publicRiverLevelView: current level, flow and threshold status by station; omits raw sensor diagnostics and provisional unvalidated values
