The mission of the Wentworth Watershed Association is to protect and preserve the Wentworth-Crescent Watershed through initiatives that enhance water quality, land conservation,

and community education. The Wentworth Watershed Association is made up of residents and landowners in the Lake Wentworth/Crescent Lake watershed in Wolfeboro, NH, as well as others who want to encourage the protection and preservation of these valuable natural resources. The Association uses its tax-deductible donations to support numerous environmental activities such as funding the University of New Hampshire’s Lakes Lay Monitoring Program, tackling problem areas identified in the Watershed Management Plan, and engaging in milfoil control. Presently the Association owns and manages 14 parcels of land totaling more than 500 acres. Information about Association activities and holdings can be found on the organization's website at www.wentworthwatershed.org. The Internal Revenue Service has granted the Association tax-exempt status under Section 501(c)(3) of the Internal Revenue Code, making contributions deductible on the donor’s federal tax return.

Our septic systems discussion will be held tomorrow. Don’t miss out!

Join us at 1:00 on August 25th in the Wolfeboro Public Library’s Bradley Room for an informative (and we have promise, not-too-stinky) workshop with Gary Spaulding of Advanced Onsite Solutions.

We’ll dig into:
💧 How failed septic systems can impact lake health
🔧 Septic maintenance and costs
🏠 Upgrading an older system and navigating the application process
📋 State of New Hampshire septic regulations
🏘️ Wolfeboro’s current initiative to develop a local septic ordinance

Understanding how septic systems work, and what happens when they don’t, is an important part of keeping excess nutrients out of our lakes.

Come with your questions and leave knowing a whole lot more about what’s happening beneath your backyard.

Are you lake minded?

We had a great time at Winnipesaukee Day. Those that visited our booth had the opportunity to sign a pledge and pose for our Photo Booth to show that they are lake minded.

Would you like to join in and pledge too? Here are some things you can agree to do moving forward to make a positive impact:

✅ I pick up my pet’s waste at home and on public lands
✅ I will infiltrate stormwater on my property
✅ I signed up for a Lake-Minded visit
✅ I will use phosphate-free detergents
✅ I will be “Wake Wise” to prevent shoreline erosion and property damage
✅ I will reduce and clean up any salt or sand I use in the winter
✅ I will use Green Snow Pro Operators
✅ I will eliminate fertilizer use on my property
✅ I will pump my septic system every 3 years

💩 Let’s talk about something nobody wants to talk about…septic systems!

They may be out of sight, but they shouldn’t be out of mind - especially when it comes to protecting our lakes.
