The Question

I am interested in hearing from people who make their own Secchi disks. I would like to know how you make them. Thank you!

Hello:

In response to Ellie's inquiry regarding making Secchi disks, I would like to offer this link to our website for our "Measuring Water Clarity" factsheet. Among other things, this pdf document includes instructions for making your own disk, as well as a primer on basic water clarity.

http://www.uri.edu/ce/wq/ww/resources/secchi.pdf

Then of course, the definative site for measuring water clarity is the "Great North American Secchi Dipin" found at http://dipin.kent.edu/.

Thanks

Elizabeth Herron
