MEREDITH (AP) — Researchers and environmental groups are holding a one-day collection of water samples of Lake Winnipesaukee to see if there's been an increase in phosphorus levels, which can lead to higher amounts of algae and lake vegetation.
Steve Landry of the Department of Environmental Services tells New Hampshire Public Radio the timing of the sampling, shortly after this year's ice-out declaration, is important. He says when it gets warmer, the lake water separates into thermal layers and it's harder to get a good reading.
Monday's event is the second large-scale comprehensive effort to sample the lake; the first was in 2010.
