In the spring of 2019, the treatment of Lake Attitash with Alum to keep the major Cyanobacteria / Blue Green Algae blooms at bay was completed. It was a great summer with no harmful algal blooms The lake water was clearer than it has been in many years. A big thank you to the Town of Merrimac, City of Amesbury, the Mass Department of Environmental Protection and those many residents and friends who donated funds to make this happen. It’s now time to make sure that we keep the nutrient levels in the lake down. Your help is needed to follow the good practices that can be found in the “Protect Your Lake” in this LAA website. Everything you do, no matter how big or small has an impact on the lake. Thank you.
