What the heck join the Secchi Dip-in
Annual Secchi Dip-In collects water transparency data

Concord, NH – The New Hampshire Department of Environmental Services (DES) is conducting the NH portion of the Great North American Secchi Dip-In. From Saturday, June 28 until Sunday, July 20, 2014, volunteers will be using Secchi Disks to collect water transparency data in the United States and Canada.

Since the Dip-In began in 1994 in six Midwest states it has expanded to include more than 41,000 records on more than 7,000 separate waterbodies. Dip-In volunteers routinely monitor all types of waterbodies, including lakes, streams, and estuaries, as a part of their normal monitoring program.

“We encourage all volunteer lake monitors throughout the state to participate in the Dip-In to once again provide valuable information on lake clarity trends of our beautiful lakes. With over 900 New Hampshire lakes, we are fortunate to have such a loyal group of monitors who provide such valuable information to NHDES and national programs like the Dip-In,” said NHDES Volunteer Lake Assessment Coordinator, Sara Steiner.

Previous Dip-In's have provided valuable information on the nation’s water quality. The maps have shown considerable regional differences in transparency. Lakes in the northern parts of the United States and in Canada typically have the clearest waters, while lakes in agricultural regions of the Midwest have some of the smallest transparencies. Transparencies found during the Dip-In range from one inch to more than 65 feet. As of 2010, more than 2,000 bodies of water have been monitored during the Dip-In for five or more years enabling trend detection. Approximately 17 percent of these had significant trends, with eight percent showing improving transparency and nine percent worsening.
