Possible online services disruption due to Internet related outage

A worldwide technology outage is causing disruption to some State of Illinois online systems.  We are aware of this issue and are diligently working on restoration.

Additional Monitoring Opportunities


The Great North American Secchi Dip-In

In addition to the duties and responsibilities of the VLMP, many of our volunteers take part in global monitoring activities, such as the Great North American Secchi Dip-In and World Water Monitoring Day.

The Illinois Volunteer Lake Monitoring Program has been a participant in the Secchi Dip-In since 1994, the first year of this event. This global event is a great way to become involved with environmental monitoring and to see your efforts reach beyond your back yard.

What is the Dip-In?

The goal of the Dip-In is to mobilize volunteer monitors to take a Secchi transparency reading one time during the weeks between Canada Day and the 4th of July. This one-time Secchi transparency reading represents a snapshot in time of water clarity which can give a national and global perspective of water quality.

How can I participate?

To participate, volunteers are asked to go to the Secchi Dip-In website and enter the Secchi transparency information they collect on their regularly scheduled VLMP monitoring trip for the first part of July. It takes only a few minutes of the volunteer’s time to make a global impact.

The Dip-In website is an extremely useful educational resource to learn about the creator of the Secchi disk, the significance of Secchi transparency readings and to better understand other water quality parameters and lake processes.

World Water Monitoring Day

In addition to the duties and responsibilities of the VLMP, many of our volunteers take part in global monitoring activities, such as the Great North American Secchi Dip-In and World Water Monitoring Day.

Like the Secchi Dip-In, World Water Monitoring Day, or WWMD, is designed to engage citizens in environmental monitoring. It is an international education and outreach program which encourages the public to perform basic monitoring on their local waterbodies.
