2nd Ever Winnipesaukee Ice Out ‘P check’ on May 4th!

Thank you  to all of the volunteers, NHDES staff, UNH, communities and businesses that made the second Ice Out ‘P check’ a success!

A flotilla of boats went out on Lake Winnipesaukee on Monday, May 4, 2015 in a massive coordination effort conducted by the Lake Winnipesaukee Association to obtain lake samples after ice out.  Ice out on Winnipesaukee was declared on April 24th, leaving a small window of opportunity to collect samples before the lake begins to stratify.  Read the article in the Citizen to learn more.

Steve Landry, NHDES, and Heidi Baker, volunteer, collect water samples in Moultonborough Bay for lab analysis of phosphorus concentrations.

“We could not make this event happen without the tremendous cooperation and support from numerous individuals, state agencies, local marinas, UNH, and the town Conservation Commissions!”  stated Pat Tarpey, Executive Director, LWA.
