Oronto Bay Beach 2 is a Great Lakes beach in Iron County, Wisconsin. Across 32 bacteria samples collected between 2021 and 2023 at nearby monitoring stations, it earns a Beach Safety Grade of A — Excellent.
About 0.0% of samples at Oronto Bay Beach 2 exceeded the EPA Beach Action Value of 235 CFU/100 mL for Escherichia coli — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was almost never crossed here over the monitored period. Bacteria samples almost never exceed the safe-swimming threshold.
Read this grade as directional rather than settled: it rests on only 32 samples and has no results reported since 2023. That is enough to classify how the water has behaved, but not enough to separate this beach from another a grade away — a beach graded from thousands of samples at several stations is a firmer read. As more results are reported, the grade may shift.
Oronto Bay Beach 2 is currently listed as inactive in the EPA beach-monitoring program, so it may no longer be routinely sampled. Its grade reflects the water-quality results collected while it was active — useful history, but confirm the beach's current status and any local advisory before you visit.
