LSPA has been concerned with
water quality since its founding in 1898, when
the issues were sawdust and trash in the lake and
the level of the lake water. In the 1950’s
LSPA collected water samples and tested for E.coli
in order to have Lake Sunapee meet the standards
to be named a class A (drinking water quality)
lake in New Hampshire.
Starting in the 1980’s, LSPA volunteer water
quality monitors have been regularly sampling Lake
Sunapee’s water in cove and deep sites in Lake
Sunapee, and more recently in its tributary streams.
The samples are analyzed in LSPA’s Water Quality
Laboratory at Colby-Sawyer College; NH Department
of Environmental Services provides an annual water
quality report based on its analysis of the data
as part of the VLAP (Volunteer Lake Assessment) Program.
The LSPA lab at Colby-Sawyer College, run by Bonnie
Lewis under strict quality standards as a sister
lab to the state lab at NH Department of Environmental
Services, also processes water samples for about
twenty five area lakes.
"Deep Siting" in lake measurements are also taken in Lake Sunapee, along with water samples from many Water Quality Monitors around the lake and its tributaries.
The New Aquatic Invasives
New Aquatic Invasives are spread in the Northeast. Zebra mussels, Asian clams and quagga mussels are among the latest "invaders" of our water bodies in NH as well as NY, VT, ME, MA and CT.
Irene and Lake Sunapee
Tropical Storm Irene did have its influence on Lake Sunapee. View the graphed data collected by LSPA's buoy.
Keeping our water clean
Keeping our water clean - LSPA and Fells volunteers and staff clean up a section of Lake Sunapee.
There has been recent local media attention to cyanobacterial (blue green algae) blooms in New Hampshire lakes.
Carey’s Graduate Work
Cayelan Carey will be continuing
the data collection work she began last
summer for her dissertation at Cornell.
How Lakes Freeze
Recently, I have had several people ask about how lakes freeze. I knew some answers, but as I researched deeper, the freezing of lakes can be complicated!

Didymo: The New Invasive
The invasive species Didymosphenia geminata, or didymo was discovered in Vermont June 25th, 2007
Milfoil prevention efforts at LSPA
Milfoil prevention efforts at LSPA began in 1998 when we established two aggressive programs (Weed Watch and Boat Launch Monitor) to provide early detection of invasive aquatic plants.
Gloeotrichia echinulata, a blue-green alga, has recently been blooming in Lake Sunapee.
Invasive Aquatic Plants
LSPA’s volunteer weed watch program discovered invasive milfoil in Georges Mills in the summer of 2001.
There are other aquatic invasive species in New England that LSPA is concerned with.
There are five general types of algae in Lake Sunapee and surrounding ponds.
Water Quality Monitors
LSPA has a long history of setting and maintaining standards of excellence in our water quality testing program
On June 16th, LSPA Lake Host made another milfoil “Save” this summer.
