Moultonborough Bay and Winter Harbor Watershed Management Plan Proposal




Moultonborough Bay Inlet Watershed Restoration Plan

On December 11, 2017, the Lake Winnipesaukee Association, in partnership with FB Environmental Associates of Portland, Maine, presented a plan to address the water quality impairments in Moultonborough Bay Inlet at a public meeting held at the Moultonborough Public Safety Building.

Moultonborough Bay Inlet, the northernmost area of Lake Winnipesaukee, has historically exhibited excessive levels of the nutrient, phosphorus, poor water clarity, low dissolved oxygen, and extensive milfoil growth.  The Moultonborough community has invested considerable resources over the past five years to address milfoil and lake quality.  The Watershed Restoration Plan identifies sources of pollutants within the watershed that have led to the impairments and results in an action plan to assist the community in guiding their efforts to improve water quality.  The presentation can be viewed here.

Lake Waukewan – Lake Winona Watershed Restoration Plan

Lake Waukewan rainbowThree years in the making, the Watershed Restoration Plan for Lake Waukewan and Lake Winona was completed on September 30, 2016.

Prepared by the Lake Winnipesaukee Association and FB Environmental Associates of Portsmouth, NH, the plan is the successor to the 2005 Waukewan Watershed Management Plan, and part of LWA’s lake-wide approach to preserving and enhancing the water quality of Lake Winnipesaukee.

Watershed residents, landowners, business owners, and recreationalists alike have a vested interest in protecting the long-term water quality of Lake Waukewan and Lake Winona for future generations.  The goal of the plan is to improve the dissolved oxygen concentrations in the bottom depths by reducing the amount of pollutants, sediments, and nutrients that enter the lakes.  The lake study advisory committee chose to reduce the median in-lake phosphorus concentrations by 10% and 5-10% in Lake Waukewan and Lake Winona, respectively, over the next 10 years.  This goal can be reached if management actions discussed in the plan are implemented accordingly.  Implementation of this plan over the next 10 years is expected to cost $324,200, and will require the dedication and hard work of municipalities, conservation groups, and volunteers to ensure that the actions identified in this plan are carried out accordingly.

This plan was partially funded by a Watershed Assistance Grant for High Quality Waters from NHDES using Clean Water Act Section 319 funds from the USEPA, with additional financial and in-kind services provided by the Waukewan Watershed Advisory Committee, the Windy Waters Conservancy, and the members of the Lake Study Advisory Committee.

The plan can be accessed on line at the Winnipesaukee Gateway website.

  • Septic System Improvement Initiative

Sign at sunsetImproperly functioning septic systems can present a public health risk and degrade a lake’s water quality, particularly when these systems are located near the shoreline. Poorly functioning septic systems can release excessive amounts of nutrients, pathogenic organisms, and pharmaceuticals into a water body. At the same time, it can be difficult to identify problem systems and enforce rules on the local level to repair, upgrade, or replace those systems, largely because of the cost to property owners. Despite these challenges, the town of Meredith and the Lake Winnipesaukee Association (LWA) implemented programs to identify and help homeowners fix failing septic systems near Lake Waukewan, which is Meredith’s public water supply and a regional recreational resource.

In January 2013, the town of Meredith adopted a health regulation that requires evaluation of all septic systems within 250 feet of  Lake Waukewan.  Also in 2013, The NH DES awarded LWA a grant through the Source Water Protection Program to provide cost sharing incentives to reimburse property owners half the cost of a professional evaluation of their septic systems.

Compliance with Meredith’s health regulation was likely enhanced by LWA’s cost share evaluation program.  Sixteen property owners voluntarily participated in the cost share program which was open to New Hampton, Center Harbor, and Meredith residents.  Seven septic systems were found to be in failure (44%), and nine passed (56%).  In addition, eight Meredith properties had their septic system evaluations done outside of the program; half of which were found to be either in failure or passing with intermittent use only.

For those properties whose septic systems were found to be in failure, LWA offered a second cost-share program toward the installation of new systems.  As of the completion date of the grant project, December 31, 2015, fourteen septic systems were upgraded and replaced, resulting in a reduction of 5.3 kg of phosphorus to Lake Waukewan, in addition to a reduction in other pollutants, such as bacteria, nitrates, and pharmaceuticals.  Of the 14 new systems installed, LWA provided cost share grants in the amount of $4000 to 9 property owners toward the overall cost.

We are pleased to have been able to offer these much needed cost-share programs to help property owners offset the financial burdens associated with septic system replacements.




Year-Round Green Tips

Anything you throw into a river, stream, or even a storm drain is going to end up in the lake. Those tiny cigarette butts are litter too. Dispose of garbage properly and, yes you are going to hear it again, “Reduce! Reuse! Recycle!” and the fourth ‘R’ – Repair!  Start the New Year off making a greater effort to reduce your trash output and increase your recycling. Save yourself time and set up a few containers in your garage to sort recycling. You may want to sort your recycling as you go along or maybe it is easier to keep a smaller container under your sink and throw all recyclables in it until it is full and then sort it in the garage or wherever you choose to place your sorting center. It’s easy. It’s simple. It’s stupid not to do it. For more information on what can be recycled and how to recycle anything from cell phones to used greeting cards go to

Don’t be the stink of the neighborhood! Make sure your septic system is not leaking or overflowing by having the system inspected every three to five years and pumped whenever necessary (a recommended 2-3 years for permanent residents and 5-6 years for seasonal residents). If you do not take care of your tank properly, settled solids might wash into and clog your leach field as well as contaminate groundwater. Not only yucky but also very expensive to fix!

Time for spring-cleaning! Buy eco-friendly cleaners such as Seventh Generation/Harmony, Ecos, Earth Rite, Ecover, and Life Tree. Dispose of any hazardous household chemicals properly, not down sewer or storm drains. By reducing the amount of chemicals going into your septic system, your system will stay balanced and avoid the risk of groundwater contamination that may poison your well water and the lake. Storm drains run directly into the lake so it is important not to “pour” oil or any other hazardous chemicals into the drain. In the Lakes Region, Household Hazardous Waste Day is held on the last Saturday in July. For more information on where and when to dispose of your hazardous waste, contact your local town office or the Lakes Region Planning Commission (603-279-8171).

Celebrate Earth Day! Plant trees, shrubs, and flowers on shorefronNH Plantst property (vegetative buffers) as well as on other exposed areas near drainage systems. Vegetative buffers help remove sediments and other nutrients from runoff before entering the lake. Runoff traveling down driveways and camp roads directly into the lake may be diverted through the woods or into a vegetated buffer. For examples of species that work well as vegetative buffers in New Hampshire environments, refer to the UNH Cooperative Extension’s “Landscaping at the Water’s Edge” publication or the “The Best Plants for New Hampshire Gardens or Landscapes”, both available through UNH Cooperative Extension.  Belknap and Carroll County Conservation Districts hold an annual tree & shrub sale in April (ordering deadline is usually in Feb/Mar) which offer a large variety of native plants to choose from. Call BCCD at (603)527-5880 or CCCD at (603)447-2771 for details.

It’s time to build little Johnny that float you told him he could swim to once he was old enough. Construct docks and floats with environmentally friendly materials. Pressure treated and painted wood have chemicals proven to be harmful to living organisms. Cedar, redwood, cypress, recycled wood/plastic, and aluminum are all safe materials to use for dock and float construction.

Quack! Quack! You may be tempted to throw those cute waddling ducks a cracker, but think twice before you do. There is plenty of natural food for the ducks to feed on. Feeding them anything not naturally occurring in the watershed will put unnecessary amounts of nutrients (duck poop) in the lake. The excess nutrients (duck poop) act as excess fertilizer, which can result in algae blooms, not to mention increasing the chances of getting duck itch.

Are your neighbors not talking to you because they are utterly disgusted at the fact your lawn is brown? Well good for you! Grass is supposed to turn brown over those hot dry periods. Don’t worry, your grass isn’t dead; it’s just dormant. The grass is taking a nap and will turn green once again when the conditions are right.

If you are using fertilizer, do not try dumping more and more fertilizer on your lawn to turn it green. Most likely there is more than one reason for your lawn not being healthy. Have your soil tested by the UNH Soils Analytical Laboratory to find out how much fertilizer and what type you really need (for more information contact the UNH Cooperative Extension nearest you). If you don’t test your soil, try adding some lime to the lawn to counteract acidity and allow the nutrients present to be absorbed by the grass. A few other tips for keeping your lawn healthy are:

Aerate the soil with an aerating machine.
Leave grass clippings on your lawn to act as a natural fertilizer and irrigate your lawn.
Keep grass long (at least 2 inches) to promote deeper roots and shade to discourage weeds.
Make sure your lawn mower blade is sharp (if the tips of the grass are jagged after mowing, you need a sharper blade).

Going on vacation to enjoy the last few weeks of the summer sun? Bringing your boat with you? Don’t forget to make sure you are not transporting any nuisance species such as milfoil into our lake or into any other lake. Inspect your boat and trailer, particularly on the rollers of the trailer and on the boat motor. Put any plant material or anything else you find in a trash bag and dispose of properly. It is also recommended to wash your boat with very hot water away from the lake, flush the motor, and let it dry for two days before launching it into another body of water.

Don’t do it in the lake! Using soap or phosphorus containing detergents to bathe, wash boats, or anything else for that matter may cause algae blooms by increasing phosphorus levels in the lake. Wash your car and boat over grass instead of paved driveways or concrete. The grass and soil will help filter out the phosphorus instead of allowing it to run directly into the lake.  And whether in the city or the country, cleaning up after “Benji” is a must so that we don’t end up swimming in his manure.

Wouldn’t it be so easy to just rake the leaves from the yard right into the stream behind our house? No mess, right? Wrong! Vegetative material will add phosphorus and other nutrients directly into the lake as well as create excellent habitat for leeches at your personal swimming area. Keep leaf piles and brush piles at least 250 feet from the shoreline or 50 feet from any other drainage. Never dump leaf or brush piles into the lake or any other drainage area such as a stream, river, or storm drain.

Be like the pilgrims and serve a free-range turkey for Thanksgiving. It’s better for you and it’s better for the turkey. Gobble! Gobble! Be thankful for the lake; join LWWA and support our efforts in protecting the lake and surrounding watershed.

Are you tempted to buy one of those tacky frosty white artificial Christmas trees just like you had growing up? You may think an artificial tree is eco-friendly because you will use it year after year, but studies show that most people get rid of their fake trees after 6 years where they end up in a landfill. Artificial trees are also made with petroleum-based products, nonrenewable resources, which produce pollution during collection and synthesis of the products. Buy a real Christmas tree grown on a tree farm where the trees benefit wildlife habitat, stabilize soil, buffer water supplies, provide oxygen, and spread holiday cheer.
