How this page sorts
Sorted by the lowest current CFU/100mL reading first, then by current status, historical risk, and sample freshness.
When to use it

What still overrides it
Heavy rain, runoff, brown water, or a stale sample can make any ranked list less trustworthy for a same-day swim call.

How To Use This View
Use this page when you want to compare the actual current reading values side by side and not just a status label.
The current sample still matters more than the label alone. When conditions are marginal or weather is changing quickly, open the individual beach page to compare sample date, current reading, and nearby alternatives before you go.
If it has rained recently, use the rain guide before trusting any beach list too much.
