AquaScope gauges

The station catalog of every water-observation source AquaScope can reach, harvested on a schedule and published as GeoParquet. Last run 2026-08-18T10:58:54+00:00 with aquascope 0.11.0: 45,919 stations from 6 of 6 sources.

Files:

stations.parquet: GeoParquet 1.0 (WKB point geometry, WGS84). One row per station: source, station_id, name, latitude, longitude, variables, period_start, period_end, url (deep link to the agency page), river, country, agency, license, redistributable, extra.
stations.geojson: the same rows as GeoJSON for tools that don't read parquet.
health.json: per-source status of the last run (station count, seconds, error if any).

Query it in place

DuckDB reads the parquet over HTTPS without downloading it:

INSTALL httpfs; LOAD httpfs;
SELECT source, count(*) FROM
  'https://huggingface.co/datasets/Rekin226/aquascope-gauges/resolve/main/stations.parquet'
GROUP BY source ORDER BY 2 DESC;

Or from Python: pandas.read_parquet("hf://datasets/Rekin226/aquascope-gauges/stations.parquet").

Sources and terms

Only sources whose terms allow redistribution will have their observations mirrored (Phase 1 of #188); every source appears in the catalog with a link back to the agency. Attribution for each source is in the AquaScope registry (aquascope.registry.SOURCES[key].attribution).

key	source	country	variables	licence	mirror observations	last run
`hubeau_hydrometrie`	Hub'Eau hydrométrie	FRA	discharge, water_level	etalab-2.0	yes	4,150 stations

Catchments (BasinATLAS, `basins/`)

The level-12 sub-basins of HydroATLAS v1.0 / BasinATLAS (Linke et al. 2019, CC BY 4.0) with their routing and attributes, so any point on land can be placed in its catchment and described: basins/lev12.fgb (simplified polygons, spatially indexed; point lookups over HTTPS read a few kilobytes), basins/lev12_topology.parquet (hybas_id, next_down, main_bas, sub_area, up_area, ... plus a representative point), basins/lev12_attributes.parquet (every BasinATLAS attribute per sub-basin, incl. the upstream-aggregated *_u* fields), and basins/lev12.pmtiles / basins/lev06.pmtiles for maps. Built by basins.yml; aquascope basins at LAT LON and the MCP tool describe_catchment read them. Cite: Linke, S., Lehner, B., Ouellet Dallaire, C., et al. (2019).

How it is built

aquascope harvest stations --out archive --publish Rekin226/aquascope-gauges runs weekly from GitHub Actions. Every collector answers stations() from its own agency API; nothing is hand-edited. Add a source to AquaScope and it appears here on the next run.
