The statewide NH Lakes Lake Host Program already made its first save on Granite Lake. Three Ponds Boaters, please make sure you inspect your boats both going in and coming out of all waterbodies! The cost of managing European Naiad in Milton Three Ponds has exceeded $600,000 over the last nine years...we do not want another invasive species coming in and we don't want our neighboring waterbodies to face the same problems. Please CLEAN, DRAIN and DRY your boats. Watch this short video (https://threeponds.net/boat-inspections/) to understand how a boat inspection works and do your part to make sure that all boats are properly inspected!
We’re both excited and alarmed to report the first aquatic invasive species interception of the summer, thanks to the vigilance of the Lake Host Program!
A few weeks ago, Lake Host Zack Rioux spotted suspicious plant fragments clinging to a boat trailer just before it was launched into Granite Lake, one of New Hampshire’s pristine, invasive-free lakes. Thanks to Zack’s sharp eye and thorough inspection, he removed several plants, potentially stopping a devastating infestation in the lake before it could start.
In the photo, three different plant species were found, and one is confirmed to be invasive in New Hampshire. While we can’t tell from the image whether it's Hydrilla or Brazilian elodea, both are harmful invaders. Our partners at the New Hampshire Department of Environmental Services couldn’t make a definitive ID either, but they agree that it's trouble.
The boat’s last launch? Spofford Lake, another invasive-free lake. Now, W**d Watchers from both the Granite Lake and Spofford Lake Associations are on high alert, monitoring shallow areas to make sure no invasive plants have snuck in.
Huge thanks to Zack for being on duty. And a round of applause to all boaters helping protect our lakes by cleaning, draining, and drying their boats, trailers, and gear between waterbodies.
