The statewide water map
Every active streamgage and groundwater well in the network, on one map. Shade the state by gages, live streamflow, or groundwater — and switch between counties and watershed sub-basins to see the data at any scale.

Tap a county or sub-basin to see its gages and live streamflow, or tap a point for a single site.
Sub-basin spatial scalability. Counties are familiar; watersheds are how water actually behaves. The same readings re-aggregate to HUC8 sub-basins instantly — the foundation for zooming from statewide totals down to a single basin as more data is added.
