Bad River Mouth East is a Great Lakes beach in Ashland County, Wisconsin. Across 536 bacteria samples collected between 2021 and 2026 at nearby monitoring stations, it earns a Beach Safety Grade of A — Excellent.
About 2% of samples at Bad River Mouth East 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 rarely crossed here over the monitored period. Bacteria samples almost never exceed the safe-swimming threshold.
The evidence behind this grade is deep for a beach page: 536 results from 14 monitoring stations, spanning 2021 to 2026. Enough sampling, from enough places, over enough seasons that one bad week can't drive the letter.
Bad River Mouth East was not under a swimming advisory in the most recent EPA snapshot. Conditions can change quickly after heavy rain or high runoff, so it's still worth checking the current advisory the day you go.
