Lake Wentworth and Crescent Lake Watershed Management Plan available at Wolfeboro Library

IMG_7218[1]On Thursday, February 5th, the Lake Wentworth Foundation donated a copy of the Lake Wentworth and Crescent Lake Watershed Management Plan to the Wolfeboro Public Library.

Jack O’Connell, President of the LWF, and Rich Masse, both major contributors to the original plan, presented the 200 page book to Cynthia Scott, Library Director.
Upon donating, O’Connell said: “This represents a terrific collection of important information about the lakes. Additionally there is a substantial amount of information that local property owners can and do use to prevent storm water runoff from polluting the lakes in the watershed.”

Masse added comments about the document’s use by students in the area: “Some of the local schools have environmental studies or other social studies classes that can really utilize this rich resource.

“This most recent plan has much more data and updated information (than a 1996 Department of Environmental Services smaller study) for those interested in local developments in the field.”
Upon receipt, Scott said that “(the document) is a wonderful contribution and we appreciate the opportunity to preserve such a resource that will be available to our community”.

The plan is timely now because several projects recommended in the report are being implemented over the next year. These storm water management projects will improve water quality in both Crescent and Wentworth lakes.

The document is being placed in the reference section for in-library use. It may also be viewed on the foundation website:
More information about the management plan or other activities of the LWF is available by contacting Karen Burnett-Kurie, Executive Director, at or at 603-534-0222.

Phosphorus: friend and foe

You can find three numbers on every bag of fertilizer. They tell you, the consumer, just how much nitrogen (N), phosphorus (P) ,and potassium (K) are in that container.

The obvious question is what numbers do you need? To answer this question, Don Kretchmer of Wolfeboro, limnologist and Certified Lake Manager, tells people to have their soil tested before applying any chemicals to a lawn, garden, shrubbery or trees. (Limnology, by the way, is the study of inland waters, and Kretchmer’s certification comes from the North American Lake Management Society.)

Why don’t I just go for the bigger numbers? Well, too much of a ‘good thing’ can in fact be bad. For example, too much nitrogen can cause a plant not to flower or bear fruit. Too much potassium can inhibit the absorption of other nutrients. This can then lead to problems caused by nutrient deficiencies. Plus, excess of any of these chemicals is free to go elsewhere, causing other problems.

The second number on the bag represents the amount of phosphorus. “Phosphorus is a necessary ingredient for plant growth. About 0.2% of a plant’s dry weight is composed of the element” according to Theodorou and Plaxton. Phosphorus provides essential components for processing nutrients as well as enzymes and other factors that contribute to the plant’s health.

But Kretchmer explains that added phosphorus in streams and lakes can, and often does, contribute to excessive growth of vegetation and algae. A common example of this is phosphorus’s role in algae blooms. Continue reading

Foundation steps out at Festival of Trees

The Lake Wentworth Foundation made its debut appearance in Wolfeboro’s annual Festival of Trees this year at the Wright Museum.

The event features elaborately decorated trees from more than five dozen civic organizations and businesses throughout the Wolfeboro community. This year represents the 16th that the festival has run.

The display of trees is open for viewing by the public on the weekends of December 6-7 and 13-14 as well as  on Wednesday evening, Dec. 10. 

Each year, proceeds from admission fees are donated to one or two local non-profit organizations. This year’s beneficiaries are End 68 Hours of Hunger and Caregivers of Southern Carroll County and Vicinity. 


The Foundation entry features a variety of winter sports and recreational items, including skates, a sled, and snowshoes, representing the availability of year-round recreation on Wolfeboro’s lakes and trails.

The display is flanked by a sign proclaiming the Foundation’s commitment to “protecting Wolfeboro’s water quality, natural resources, and scenic beauty.”

Trolley tour highlights increasing watershed protections
