Executive Order 25-63 · Directive #4
See the water Indiana is measuring, right now.
One public front door to Indiana's rivers and aquifers: live streamflow, groundwater levels, watershed trends, and plain-language answers, pulled together from the agencies that already measure them.
Try “Wabash River”, “Marion County groundwater”, or “how many streamgages are in Indiana”.
A redesign concept by Stoa Works, built on live public USGS, Census, and federal data to show what Indiana's On-line Water Data Portal could be. Not the official State site.
Live from the U.S. Geological Survey · last refreshed —. Demonstration data for a concept portal.
The whole state, one map
Indiana's water, by county or by watershed
The same live network, re-aggregated on demand. Toggle between counties and HUC8 sub-basins to see streamflow, groundwater, and gage coverage at the scale that matters to you — a working demonstration of sub-basin spatial scalability.

Why this portal
Indiana decided its water deserves a single, public view
In 2025, Executive Order 25-63 directed a statewide water inventory and management plan. Directive #4 calls for a centralized, publicly accessible platform sharing real-time water data, usage trends, and infrastructure status — shaped by six regional workshops and more than 300 Hoosier stakeholders.
Real-time, in one place
Surface water, groundwater, and watershed context together — no hunting across agency sites.
Built to grow
An integration layer ready for NWS forecasts, the Purdue Mesonet, and DNR well-log and withdrawal data.
For everyone
Planners get depth; the public gets plain answers and conservation education.
