The 2013 Maine Lakes Report is available online, in color. The Maine Lakes Report is Lake Stewards of Maine’s annual report, and summarizes Maine lake data with an overview of lake water quality and invasive aquatic plants. The report also includes an update of lakes with certified volunteer monitors. For a hard copy of the Annual Report contact us.
Please note: Due to several factors beyond our control, there was no report issued for 2014. The 2015 Maine Lakes Report will be issued in 2016.

The Secchi disk is a simple but effective tool used by lake scientists worldwide to measure the clarity (aka: transparency) of lake water. Taken at regular intervals, Secchi readings provide a reliable indicator of overall lake health.
The LSM Secchi Simulator is an innovative tool developed to enable volunteer citizen lake scientists to meet recertification requirements online, reducing the frequency, and therefore the time and expense, of in-person recertification. It has been shown to be an effective means of ensuring that volunteer monitors gathering water quality data are using the proper protocol and that their readings meet a specific standard.
The Simulator includes both taking a virtual Secchi reading and a series of multiple choice questions designed to gauge understanding. Their responses and official Secchi reading are entered into the LSM volunteer database.
The Secchi Simulator is also available to the general public as a learning tool, and is being used by a number of citizen lake monitoring networks throughout the country.

To Ruling Out Maine’s 11 Most Unwanted Invasive Aquatic Plants
Quick Keys are now in stock and available for purchase!
The Quick Key is a convenient pocket sized guide to ruling out Maine’s eleven most unwanted invasive aquatic plants. Each quick key costs $1.50, and there is a 10 % bulk discount for orders with quantities of 100 or more. To order a guide, please contact email@example.com.
The Field Guide focuses on the eleven invasive aquatic plants currently listed by Maine law as imminent threats to Maine waters.

Identify plants using the online interactive Field Guide to Maine’s Aquatic Invaders
Set upon the backdrop of one of Maine’s most extraordinary lakes, The Hunt for Aquatic Invaders takes the viewer on a very different kind of outdoor adventure, one that not only speaks to the urgency of the task of preventing the spread of aquatic invaders in Maine, but also provides guidance and inspiration as it explores the vital role that volunteers can play in local and statewide early detection efforts.
Once an infestation has been confirmed, rabid response is crucial. The prospects for effective management or even eradication is greatly increased by swift, well-planned, and properly executed controls. The purpose of the Maine Citizens’ Guide to Invasive Aquatic Plant Management is to provide the information necessary to effectively manage invasive aquatic plant (IAP) populations, to prepare for such an eventuality, and to address all associated activities. Methods described in this Guide are based upon tested best management practices for controlling aquatic plants effectively and in a manner that protects wildlife and habitat.
The Friend or Foe? Learning Kit has been designed to provide a quick, easy, hands-on method for teaching people with no previous plant identification experience how to quickly determine if a plant in question is a “friendly native” or a “suspected invader.” The Kit contains a collection of several true-to-form plastic plants (some representing invasive species, others, harmless natives), a set of 25 Quick Keys to Ruling Out Maine’s Eleven Most Unwanted Invasive Aquatic Plants, a self-guided practice sheet (that may be reproduced for students, or simply used by the instructor to guide the activity), and a host of other resource materials, including an instructor’s guide with background information and additional, hands-on invasive species lesson plans. At the conclusion of the exercise, it is recommended that participants keep their Key. (The handy, waterproof, pocket-folded keys may be re-ordered at low cost from Lake Stewards of Maine.)
If you are interested in participating purchasing this kit, please contact Lake Stewards of Maine (LSM) at email@example.com or 207-783-7733.
