streamflow context, rainfall 30 day, monitoring coverage use compatible measures. Other series remain separate.

About this comparison

Comparable data available

At least one shared metric has matching unit, period, and methodology.

There is no single score for water here. More measurements do not mean better or worse water, and these comparisons do not rank safety.
