Measurement
Dates/Process
Lake measurements are taken roughly every two weeks. They are submitted to the Wisconsin DNR for recording.
Lake measurements are taken, weather permitting, from April through November!
The colors and arrows on the dials show current measured value for each metric, based on last available data.
The dials on this site are updated approximately every 2 weeks depending on weather conditions.
The current goals for Delavan Lake water quality were established as part of a University of Wisconsin Water Resources Management Workshop conducted in 1986. However, they are currently being re-evaluated based on updated conditions.
