# Manitoba Hydro ArcGIS Server Reference Data

**Canonical:** https://apis.io/apis/manitoba-hydro/manitoba-hydro-arcgis-server-reference-data/

Manitoba Hydro ArcGIS Server Reference Data is one of 4 APIs that [Manitoba Hydro](https://apis.io/providers/manitoba-hydro/) publishes on the [APIs.io](https://apis.io/) network. This API exposes 3 JSON Schema definitions. Tagged areas include Geospatial, ArcGIS REST, Reference Data, and Grid. The published artifact set on APIs.io includes an API reference and 3 JSON Schemas.

An ArcGIS Server 10.91 REST services directory hosted on Manitoba Hydro's own domain at maps.hydro.mb.ca, readable anonymously. The root listing returned nine folders (ARL, ConTrack, DISTAPPS, GDS, JUTA, LEA, Locators, ReferenceData, Utilities); most are empty to an anonymous caller, but ReferenceData/MH_AdminBoundaries is fully readable and exposes three query-capable layers — MH_CustomerServiceCentres (19 features), MH_LocateAreas and MH_StationAreas. The site root itself returns HTTP 403; only the /arcgis/rest/services tree responds. Manitoba Hydro publishes no documentation, index, or terms for this host — it is recorded here because it is a real, on-domain, anonymously queryable API surface, not because it is offered as one.
