Beach Swim Advisories

This dataset is historical-only. A similar dataset starting in 2017 can be found at data.cityofchicago.org/d/xvsz-3xcj -- The Chicago Park District issues swim advisories at beaches along Chicago's Lake Michigan lakefront based on predicted E. coli levels. This dataset shows the predictions and whether a swim advisory was issued due to the predicted E. coli level being at least 235 Colony Forming Units (CFU) per 100 ml of water.

The data used to make the predictions can be found in data.cityofchicago.org/d/qmqz-2xku and data.cityofchicago.org/d/k7hf-8y75. The measured E. coli levels determined later can be found in data.cityofchicago.org/d/2ivx-z93u.
