2026 MLPOA Lake Ed Day a Great Success!
It was simple math on the lake on June 4th, 2026! 8 pontoon boats captained by Lake Monomonac volunteers + 6 NH DES Limnologists armed with water quality testing gear + 30 curious 5th graders from Rindge Memorial School = a great day on the lake for MLPOA’s Lake Ed Day.

It was exciting to see how curious and engaged this group of 5th graders were. They tested the water quality on the lake with the education and guidance from the Limnologists.

Spring Clean-Up with Care!
TIP: Wait to rake! Beneficial animals like salamanders use last year’s leaves to stay warm until they can make their way to our lakes and ponds. When nights stay above 50F, dispose of yard waste like leaves and grass clippings properly away from lakes, streams, or storm drains.

WHY: Organic material adds excess nutrients to lakes, promoting harmful algae blooms.
