Working prototype by Stoa Works — a concept for Indiana's On-line Water Data Portal, not the official State site.

Data sources & integration

The portal's value is connection: it brings authoritative water data from many agencies into one place, without replacing any of them. Here is what feeds it, and how.

Connected and planned sources

Integration approach

  • Read-only connectors to each source's public API or service — the portal never becomes the system of record.
  • A normalization layer maps every source to common site, reading, and geography models, so a new source is a configuration, not a rebuild.
  • Compatibility-first with the IGIO Esri Enterprise portal, so the State's authoritative GIS layers stay authoritative.
  • Scheduled refresh with provenance: every value carries its source and timestamp.

Out of scope, by design

  • Replacing existing agency databases.
  • Deploying new monitoring infrastructure.
  • Statewide water allocation or regulatory systems.

Matching the boundaries the RFI sets — this is a public-facing data and dashboard layer, not a database or regulatory rewrite.
