All Aboard the Floating Classroom!Floating Classroom

The Winnipesaukee Watershed Association is excited to ‘launch’ a new program this summer on the Big Lake!

Join us on a lake ecology cruise aboard our new Floating Classroom!  Beginning July 1 and running through Sept. 5, educational cruises will be offered on Tuesdays and Thursdays each week throughout the summer.

The ‘Floating Classroom’ is a fun and informative hands-on lake ecology program for adults, children, students, and summer campers who are interested to know what shapes Lake Winnipesaukee’s natural beauty.  The tour features a 90 minute boat excursion on a pontoon boat, where participants will learn fun and interesting facts about the history, geology, and ecology of the lake, as well as more serious threats and water quality issues facing the lake.  Passengers will have an opportunity to ‘be the scientist’ through collecting water samples, measuring water clarity, and determining what’s living below the surface with our underwater camera.

Please plan to join us on August 18th for our Annual Meeting.

This year we’ll be holding our meeting on the M/S Mt. Washington at 5:00pm, approximately 1 hr.  before it departs for its ‘Elvis Tribute’ dinner/dance cruise.  Stay after the meeting and enjoy a sunset cruise on Lake Winnipesaukee while enjoying dancing to Annie and the Orphans and an Elvis impersonator.   $49 ticket price includes dinner and dancing; $10 discount is available to adults 60 yrs. and older.

Attendance at the Annual Meeting is free, but we will be offering $20 off the price of the cruise  to the first 50 members who register and attend our Annual Meeting.  We’ll also be holding a Silent Auction aboard the M/S Mt. Washington during the evening cruise to raise funds toward our Floating Classroom.

It’s sure to be a lot of fun, so please reserve your spot today!  Members must be in attendance at the annual meeting to receive their $20 discount coupon.
