Webinars

Lake Dynamics

Introduction to Lake Modelling - the first half of this webinar is an excellent review of lake dynamics.
 

Wildlife

Eagles and NH Lakes - The sight of eagles soaring over our lakes is becoming a more and more common occurrence here in New Hampshire.  Find out how the population of eagles is recovering throughout the state and what you can do to help!
Otters, Beavers, Turtles & Frogs
Loon Monitoring & Recovery in New Hampshire  - Presented on Wednesday, July 29, 2020 by Caroline Hughes, Outreach/Volunteer Coordinator, Loon Preservation Committee, and Harry Vogel, Senior Scientist and Executive Director, Loon Preservation Committee
 

Living on a Lake

Lake Friendly Living - Webinar Series  These webinars cover ways in which we, as homeowners on the lake, can live "smart" and maintain the pristine conditions  that we, and all that use the lake, enjoy. They show how to create a landscape that is beautiful, functional and protects our lakes, how maintain your septic systems so that they don't pollute our lake, and how to maintain gravel roads and driveways to reduce polluted runoff water that flows into our lakes,  and streams. 
 

Climate Change

NH's Changing Climate and Lakes - The climate in New Hampshire is changing. Find out how and what this means for our water resources and our lakes.

Influence of Warming Climate on Aquatic Invaders in Maine Lakes -This is a fascinating and sobering presentation by Roberta Hill to the Lake Stewards of Maine and very relevant to our lakes in New Hampshire. Our northern lakes have historically been protected to some degree by a relatively cool climate. Many species of invasive flora and fauna that have successfully infested lakes throughout much of the US have failed to gain a foothold in the Northeast, in part due to our long, cold winters, and cool water temperatures. Roberta Hill provides an overview of the affects of climate change upon Maine lakes (and by association New Hampshire Lakes), and discusses the implications for local native lake communities.

 

Invasive Species

An Overview of New Hampshire's Weed Watcher Program by Amy Smagula -This is an excellent talk by Amy Smagula from the New Hampshire DES on the importance of, and how we go about our work, as volunteers surveying for invasive aquatic plants.  Click here a copy of the slides that accompany her talk.

Filamentous Algae (Metaphyton) in Main Lakes: A Presentation from Lake Stewards of Maine - For more than a decade, public anecdotal observation has suggested that  green filamentous algae, has been increasing in Maine lakes. But is it – and if it is, should we be concerned? Citizen scientists can play an important role in answering these persistent questions.

Cyanobacteria in NH Lakes  - Watch this webinar and find out what cyanobacteria is, what blooms look like, and what they tell us about the health of our lakes. You’ll also learn what is being done across the state to prevent and monitor for these harmful blooms and what to do if you think you’ve spotted one.
