A dated snapshot of the water-visibility research project

This research snapshot was generated on August 4, 2026. It is not a current gauge-status report or a measured water-visibility forecast. The usable Atlas now covers 15 places; Atlas coverage is separate from this model research.

Gauge status, plotted where the rivers actually meet the coast

Gauge coordinates and statuses from the August 4, 2026 research snapshot. Ringed markers identify the two rivers used by that model experiment, not current verified operating status.
