Beaches

The City of Rochester Parks & Recreation maintains two public beaches.

Foster Arend Beach and Cascade Lake Beach waters are tested weekly for bacteria levels (3 samples are taken at each body of water). Swimming recommendations will be posted here based on the test results. 3 levels will be used:

  • GREEN - bacteria levels are low
  • YELLOW - bacteria levels are elevated, swimming is not recommended (warning signage posted)
  • RED - bacteria levels are very elevated (single sample over 1260 organisms per 100 mL of water), beach is closed, swimming strongly discouraged (BEACH CLOSED signage posted)

Bacteria levels may increase for a variety of reasons, including runoff after a large rainfall event, wildlife in the area and hot weather.

Current Statuses

  • Cascade Lake Beach: GREEN as of 8/22/2025
  • Foster Arend Beach: GREEN as of 8/22/2025
