Fernald Brook protection aims to reduce soil runoff


Implementation of the Wentworth/Crescent Watershed Management Plan is taking another step forward as project organizers begin an effort to protect Fernald Brook, one of the largest tributaries to Lake Wentworth, from the effects of stormwater runoff.

Officials from the Lake Wentworth Foundation, the Town of Wolfeboro, and the project’s lead engineering firm, Tighe and Bond, dug a series of test pits on April 13 behind Auto Care Plus (formerly Trites Automotive and Miller Chevrolet) to determine how best to capture storm runoff from the parking areas that cover the property. During rainstorms and snow melt, water flows across the lots and towards Fernald Brook, bringing with it the potential for sand and contaminants from nearby roads to reach the stream.

Foundation names Cole as Executive Director

The Lake Wentworth Foundation has appointed Robert Cole as their Interim Executive Director.   Cole moves from his role as a Foundation trustee, where he served on the Development and Nominating & Governance Committees.

The Foundation enters its 20th year side-by-side with the Lake Wentworth Association, emerging in recent years as a proactive conservation group with a mission “to protect and preserve the water quality, natural resources and scenic beauty of Lake Wentworth, Crescent Lake and their watershed, now and for future generations.”  

 In 2012, the Foundation, in partnership with town and state organizations, completed the Lake Wentworth/ Crescent Lake Watershed Management Plan.  Projects are underway to implement the many recommendations of the plan, all aimed at a 15% reduction in phosphorus, the most prominent threat to water quality.

Winter’s impact on water quality: de-icers and sand


It is important to remember that streams continue to flow, ponds and lakes continue to ‘live’ under their ice and our responsibility to maintain healthy water ecosystems continues throughout the winter. During significant snow and ice storms, road safety requires the application of salts to melt ice and provide safe traction. Each winter local road departments, commercial parking lot owners, home contractors and homeowners use salt to melt snow and ice and to maintain road and other surfaces.

Where is even more care needed?

shoreline buffer  If you live on shoreline property, maintaining and designing your septic system requires more care than a system located elsewhere. Water pollution can happen even though your system appears to be working well and complies with local health department codes.  Indicator dye put into your septic tank  can help to find problems that may otherwise be difficult to notice.

It’s important to remember, most wastewater treatment happens in the soil below the drainfield in a traditional system. Septic systems on shoreline property are often close to both groundwater and surface waters, and drainfields are sometimes saturated during high water periods. In this case, partially treated wastewater can easily enter adjacent lakes, ponds and streams. Also, as shorelines erode, the distance between the septic system and the shoreline decreases.

What are they talking about?


Both Lake Wentworth and Crescent Lake are categorized as ‘oligo’ lakes. What the heck does this mean?

First “oligo’ is short for Oligotrophic. If you separate the two parts of this word you have “oligo” which means very little; and “trophic” the root of which is ‘trophy’ meaning nutrients. So an oligotrophic lake is one that has relatively little available nutrients. The nutrients they are primarily referring to are phosphorous and nitrogen.

Scientists classify lake types so they can be easily referred to and their basic characteristics conveyed. In this case scientists are characterizing the fertility of the water body = it’s trophic state.

All lake users and watershed residents (seasonal or year round) need to do their part to keep these lakes in their present oligotrophic states.
