GREAT NEWS!!!! No Exotic Weeds in Spofford Lake!!!!   


On 9/12, Mike Lennon, an ACT biologist along with  Pam Walton, Steve McGrath, and Val Starbuck searched the lake for invasive aquatic plants. The day could not have been more perfect-----great sunshine and the water was like "glass".  With conditions this exceptional, the team had wonderful viewing of the entire shoreline, outlet, island, and all of the "rocky" islands.  Michael was "amazed" at how few native weeds Lake Spofford has.  But, he said, the native weeds we do have are beneficial to the lake and may actually help keep milfoil from taking root.  He was happy to report that he can virtually guarantee us that we have no exotic weeds in our lake.   The SLA is proud of the contribution that its weed watching and Lake Host programs have made to this result over the past 12 years.  Now, we just have to continue to be diligent each year because hydrilla and milfoil are on the rise. 

 

Michael also measured that Lake's water clarity at 24 1/2 feet.  He said, that of the many lakes he visits in Vermont, New Hampshire, and Massachusetts, that Spofford Lake is one of the clearest he has seen.  One reason is that there is practically no development going on in the hills surrounding the lake which means less erosion and silt runoff.  His written report and pictures of native plants in the lake will be posted in this section when received. 


Invasive aquatic plants are the #1 threat to the recreational quality of Spofford Lake and to the value of your property. An effective ‘Weed Watcher’ program is the best way to keep Spofford Lake clean, clear, and unspoiled by invasive plants

 

In her recent  presentation, DES' Amy Smagula made it clear that our Weed Watch Program is the most important method we have to stop an infestation of invasive plants at Spofford Lake

 

  Exotic weeds continue to grow in waterbodies all around us and, each year, the Lake Hosts find specimens of exotic weeds (mostly milfoil) on boats and trailers.  These “catches” were kept out of the lake.    There is no way to tell if, or how many, exotic weed pieces we are missing and actually end up in the lake.  Other NH lakes & ponds are becoming infested with exotic weeds each year.

 

It is imperative that we “ramp up” our efforts in the boat launch areas and also insure that we are covering the rest of the shoreline (including the island) completely.   Amy stated that the areas surrounding the boat launch will probably be the first sections to see exotic weed clumps.  If these clumps are not found within 2 years, the growth will be enormous and we will struggle to eradicate the weed.

 

  In addition, Amy suggests that we should add May and October to our Weed Watch Schedule because milfoil still grows in cold water.    Because some of you are seasonal residents, we will need to find people to cover your sections for these 2 months.

Don’t fret the cold water……….conducting searches from small boats is perfectly acceptable (that’s how Amy does it).

 

Please help. WE NEED MORE WEED WATCHERS. Volunteer to do the Weed Watch on the lake  nearest your property. If that's covered, contact SLA. The boat launch is the area of highest risk of infestation.   The future of our lake depends on the diligence of our Weed Watchers.
