2014 Secchi Dip-In

June 28 - July 20, 2014


Welcome to the annual event where  volunteers contribute to our understanding of water quality in the world. 

Volunteers have been submitting information during  the annual  Dip-In snapshot since 1994.

Please Join Them In This International Effort to Track Changes in Water Quality


The concept of the Dip-In is simple:

Individuals take a measurement on one day during the weeks surrounding Canada Day and July Fourth.  

Individuals monitor lakes, reservoirs, estuaries, rivers, or streams, but they must already have the equipment and training.  Most are members of a volunteer or professional monitoring program. 

When 5 or more years of data have been gathered on a site, it is used to determine trends.  Over 2,000 waterbodies are now tracked for trends in transparency.

We accept data from any year. If you missed previous Dip-Ins, you can still add your data.

 We also accept data from any date during the year.  We welcome small programs to use use our database as a data depository
