Great North American Secchi Dip-In
Location: Varies
From June 26 until July 18, 2004, the Great North American Secchi Dip-In celebrates its 10th anniversary of collecting transparency data. The Dip-In began in 1994 as a pilot study in six Midwest states with funding from the US EPA's Clean Lakes Program. Since then more than 375 programs and 10,000 volunteers in the U.S., Canada, and several other countries have generated 30,000 records. This data is used to map regional differences in transparency and to detect trends. Individuals and monitoring programs are encouraged to use the Dip-In as a midsummer event to draw attention to their monitoring efforts. The Dip-In website contains all the information needed to participate, data and trend analyses from past years, and technical information on different methods of measuring transparency.
