Nearly all of those bodies of water are closed due to harmful bacteria or algae levels, the dashboard indicated.

Bacteria levels can rise for several reasons, including heavy rainfall, algae blooms, and sewer overflows.

If a beach is closed, health officials urge people to stay out of the water to avoid potential illness, as swimming in unsafe waters can result in gastrointestinal and respiratory health issues.

The state conducts water quality testing from Memorial Day through Labor Day.

Most closures last one to two days, as laboratory testing of water samples typically takes about 24 hours.
