Citizen Lake Monitoring Network
The Citizen Lake Monitoring Network, the core of the Wisconsin Lakes Partnership, creates a bond
between over 1000 citizen volunteers statewide and the Wisconsin DNR. Our goals are to collect high quality data,
to educate and empower volunteers, and to share this data and knowledge.
- Remote sensing highlights
Volunteers measure water clarity, using the
Secchi Disk method, as an indicator of water quality. Volunteers may also collect chemistry, temperature, and dissolved oxygen data, as well
as identify and map plants or watch for the first appearance of Eurasian Water Milfoil
near boat landings.
In addition, satellite images are used to retrieve water clarity data for lakes across the state.
This effort began in 1999 when the University of Wisconsin-Madison Environmental Remote Sensing Center
(ERSC) developed a model for the retrieval of water clarity data from satellite images and
Citizen Lake Monitoring Network volunteers provided on-the-ground Secchi data to calibrate this
model for each satellite image. Water clarity data was retrieved for over 8,000 lakes statewide between
1999 and 2001. The DNR continues to analyze data in this way today in its remote sensing program.
