Water Testing

Here are the latest results┬áregarding Lake Beulah’s water quality.

Secchi Testing

Every year, volunteers collect water samples using Secchi Disk readings from lakes in Wisconsin. This data is calibrated with a mathematical model and satellite imagery to achieve the most accurate readings of water quality on over 8000 lakes in the state.

The Wisconsin DNR uses data from both the Landsat 5 and Landsat 7 satellites; volunteers schedule their testings based on the day that the satellite passes overhead.
