After answering several inquiries regarding our success at eradicating weeds from Sluice Pond and raising funds to establish weed control, I thought an article describing a successful process would help others in Massachusetts and New England.

A brief history-Sluice Pond is a 50+ acre body of water with approximately 165 homes that abut the pond. Sluice Pond, fed by the Cedar Brook and natural springs, is one of five ponds located 10 miles Northeast of Boston that meander in a “Strawberry Necklace” through Lynn, MA to the Atlantic. There is a public boat ramp in a northern cove at Briarcliff Lodge that enables the general public to access the pond for boating, fishing and swimming from their boats.

The pond has 12 deeded right of ways that each enable about 65 property holders on nearby parcels to egress (enter or leave the pond). These pond paths were once water access paths for cattle, which were deeded to neighbors when older farms and estates were divided into building lots. Basically, there is a good deal of access to the pond as a four seasons recreational resource for both the general public at the boat ramp and through deeded egress for neighbors via the paths. The same public access is true at neighboring Flax Pond, which has a public beach for swimming. These access points helped us to qualify for public funding.

Evaluation & Water Level

Last summer Sluice Pond was at the lowest water level in 20 years due to a new gate system that remained open and there was tremendous weed growth. Preliminary research (backed by the experts in the evaluation process) showed that some of the rapid weed growth might be due to the low water level, which enabled more sunlight to hit the ever present weeds on the bottom of the pond in a greater number of places than usual causing rapid growth along the shore.

This year the Sluice Pond Association designated a Gate Liaison who communicates regularly with the local water commission and the water level has been much higher. Consequently, there are fewer weeds visible than this point in the summer last year, even in the coves which are largely overgrown by now. No treatment for weeds has taken place yet. We continue to record and investigate water level weed control. Weeds are also plants and respond to fertilizer run off from abutters lawns, so we have initiated an effort to ask abutters to please not fertilize near the lake edge.

After several discussions regarding the abundant weed growth last summer, we called Aquatic Control Technologies, ACT (there are only two weed treatment groups in the state). ACT had been the choice in 2001 when the pond received a chemical treatment. ACT sent an evaluation team upon request, a free service. They went around the shoreline in a boat last November to inspect the weeds and to provide us with an evaluation of the types of weeds present. They gave us a preliminary estimate for the treatment. I wrote up a summary of everything they said including that we did not have Milfoil, a weed that has been treated successfully biologically with weevils that eat the weeds and die. Other weeds don’t have these biological solutions, like weevils that eat Milfoil.

Our weeds included native Broadleaf and other invasive weeds (brought in by boats), but not Milfoil. The Milfoil was successfully treated by ACT in 2001 and has not returned. Dredging was discussed since that was the choice method 25 years ago for one of our coves. Today it’s too costly and not as effective as the chemical treatments available. ACT also provides dredging services, but not often on larger bodies of water now that safer chemicals are available. Sluice Pond is not a drinking water supply pond, so our estimate was much less than the hundreds of thousands of dollars in estimates for some communities that are trying to treat their water supply ponds.

All of the chemicals ACT proposed using have been EPA tested and approved with no detectable effect on fish or wildlife in proper doses. The application requires 1-3 days of no swimming, fishing or boating and no use of the lake water for irrigation for 90 days. Since Sluice Pond is not in an endangered species zone; all that was required was a permit from the state DEP and approval of the local Conservation Commission. The license is good for 3 years in this state. It helped that our local city councilor works for the state in environmental protection. We received the information we needed easily regarding the permitting process, the application and the timeline for hearings. He helped manage the timetable for local hearings with the Conservation Commission.

Methane is a gas found on most planets with atmospheres. In limited amounts, it isn’t a particularly problematic gas. In larger amounts, however, it can become a regulator of atmosphere temperatures.

Methane and Potential Impacts on Global Warming

Methane is fairly common gas found in nature. It is produced from both natural elements of the biomass cycle and artificial industrial sources. Methane is classified as a greenhouse gas and is believed to contribute to global warming.

Methane (CH4) is a problematic greenhouse gas for a variety of reasons. First, it has a long life once it is in the atmosphere, to wit, it will remain suspended in the upper atmosphere anywhere from nine to 15 years depending on climatic conditions. Second, methane is much more lethal when it comes to trapping heat in the atmosphere, being as much as 20 times better at doing the job than the much discussed carbon dioxide.

The unique chemical makeup of Methane is what makes it a problem. Once it gets situated in the upper atmosphere, it acts as a sponge for infrared radiation being reflected from the planet towards space. By doing so, it acts as a gas coat around the planet, heating us up as time passes. Since we can count on it sitting in the atmosphere for roughly 10 years, massive accumulations of methane can have a devastating impact over time.

Earth the great giver. What can we learn from the Earth? The world celebrates earth day in different ways. In the United States of America, it is observed on the 22nd April, while the international earth day is celebrated on the day of Vernal Equinox .

The day is observed to make all of us aware of our responsibilities towards our mother earth. The way we have been taking all that we can from the earth will one day finish all the coal and hydrocarbon from the earth. Same with all the minerals. We are extracting what all we can. The earth is our greatest friend but we earthlings behave as if we are the masters. The earth supports us in all the ways. It gives us the atmosphere to breathe, the water to drink, and food to eat. It gives us thousands of varieties of plants and it gives us the place to make our home. The earth gives its all to us without any protest.

Global warming over the next half-century could put more than a million species of plants and animals on the road to extinction, according to an international study

Thomas, lead author of the study published in the science journal Nature, said emissions from cars and factories could push temperatures up to levels not seen for 1 million to 30 million years by the end of the century, threatening many habitats. The sweeping new analysis, enlisting scientists from 14 laboratories around the globe, found that more than one-third of 1,103 native species they studied in six regions around the world could vanish or plunge to near extinction by 2050 as climate change turns plains into deserts or alters forests.

Global warming is widely blamed on rising concentrations of carbon dioxide in the atmosphere linked to emissions of gases from burning fossil fuels in cars, factories and power plants. We can cut global warming pollution by reducing pollution from vehicles and power plants.
We can increase our reliance on renewable energy sources such as wind, sun and geothermal. And we can manufacture more efficient appliances and conserve energy.
