- For
- People tracking river, flood, or low-water conditions
- Worth noticing
- The interface exposes draggable, resizable, collapsible panels, but its data view currently displays “Something failed.”
Field notes
The interface gives instructions for dragging panels by their headers, resizing them from a corner, and double-clicking to collapse them. The alert form makes state or region optional; its accompanying copy says the project stores only email and region and provides a one-click unsubscribe, though these are statements on the page rather than independently verified practices.
