About the Dip-in

The 2008 Secchi Dip-in is here! It is June 28 - July 20, 2008. The Dip-in is an annual event sponsored by Kent State University. Volunteers from all over the US (and even the world) take a secchi reading during this time. Bob Carlson, a professor at Kent State, who developed the Trophic State Index (TSI), analyzes the data at a national level to look for trends.

The Secchi Dip-in is:
  • Open to anyone who monitors water
  • A good way to publicize your activities
  • A way to contribute to one of the world's largest all-volunteer water quality monitoring efforts
  • Enables you to compare your data with others from all over the world


How do I participate?

Participating is easy. During the Dip-in, just take a Secchi reading (or participate on as many days as you want) and report your data to the Wisconsin DNR as you normally do. Optionally, you can also report your information for this time period on the Secchi Dip-In Web site (See instructions here). However, even if you don't, we will provide your data to the Secchi Dip-in.
