The Boon Family’s annual effort to remove trash from the bottom of Fourth Lake inspired MTC and may inspire you as well! Read their story and more!

Measuring Lake Water Clarity 

A Secchi disk is an 8-inch disk with alternating black and white quadrants. The disc is lowered into the lake until it can no longer be seen by the observer. This depth of disappearance, called the Secchi depth, is a measure of the transparency of the water.

Transparency can be affected by the color of the water, suspended sediments and algae. Transparency diminishes as color, suspended sediments, or algal abundance increases. Water is often stained yellow or brown by decaying plant matter. Algae are small, green aquatic plants whose abundance is related to the amount of plant nutrients, such as phosphorus and nitrogen. Therefore, transparency can be affected by the amount of plant nutrients streaming into the lake from sources such as septic tanks, sewage treatment plants, and lawn and agricultural fertilizer. Suspended sediments are often due to resuspension from lake bottoms, construction sites, agricultural fields, and storm runoff.

Transparency is an indicator of the impact of human activity on the land surrounding the lake. If transparency is measured throughout the season and from year to year, trends in transparency can be observed. Diminishing transparency can signal an early warning sign that human activity is negatively impacting the health of a lake.

MTC produced 14 Secchi disks for participants to share.  Sign-up here if you are interested in measuring water clarity for your self-directed project. Adults only. Children require adult supervision.

Wildlife Protection

Thousands of birds are injured or killed each year due to fishing line entanglement.  Heroic staff from the Adirondack Center for Loon Conservation detangle a bird caught in fishing line (top left). The Department of Environmental Conservation warns that loons are at risk for lead poisoning due to ingestion of lead fishing weights (bottom photo). 

Lead fishing weights removed from the stomach of loons.


As essential pollinators, monarch butterflies do an incredible job of helping native plants reproduce- they’re the life force behind many of our North American habitats! In 2020, the U.S. Fish and Wildlife Service announced that they would be listing monarch butterflies as endangered or threatened under the Endangered Species Act. Milkweed is the only plant larvae and caterpillars eat. Protect our milkweed and let the larvae and caterpillars thrive. Also, monarch adult butterflies eat all kinds of flowering plants.  Plant a pollinator garden to save our monarch butterflies.  

Upcycle your trash and give back to Mother Earth by creating easy-to-make seed bombs. Blend together used scraps of construction paper, water, and wildflower seeds in a food processor (adult-supervision please), then form into tiny muffins. Let dry and then toss in the ground. As the seed bombs receive sun and rain, the paper will eventually compost and the seeds will germinate.  For more ideas on upcycling your trash visit

Mowing your lawn less creates habitat and can increase the abundance and diversity of various pollinators. One way to reduce mowing is by participating in No Mow May. The goal of No Mow May is to allow grass to grow, unmown, for the month of May, creating habitat and forage for early-season pollinators. 


Left: Harmful Algal Blooms (HABs), rapid accumulation of algae in lakes that can be harmful to both wildlife and humans. Common colors are green, blue-green, yellow, brown, or red.

Middle: Eurasian Milfoil, is an invasive aquatic plant that destroys ecosystems. Due to the dense mats that it forms, it often makes activities such as boating and swimming difficult or impossible. Furthermore, clusters of these plants serve as breeding grounds for mosquitoes. 

Right: Zebra Mussels are an invasive, fingernail-sized mollusk with dark, zig-zagged stripes on each shell. Zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they attach to--and incapacitate--native mussels.

Middle: Spotted Lantern Flies are in invasive pest from Asia that feed on a variety of plants such as maple and walnut trees, and thus pose a significant threat to New York's agricultural health. 

Right: Phragmites, also called common reed grass, is an aggressive wild grass that overtakes wetlands and roadsides, growing as tall as 15 ft. These grasses impact views, damage infrastructure, and reduce property values (Courtesy of Adirondack Council)

The gypsy moth, now called the spongy moth, appeared in great numbers last year (2021) in the Eastern Adirondacks. The numbers were so great that the sound of them eating and defecating was audible in some places, providing one of nature’s creepier soundtracks. The caterpillars surge every 10 to 15 years or so, but healthy trees can generally survive a couple of years of defoliation.
