During the summer months the Squam Lakes Association conducts the Squam Keepers program in order to increase SLA presence on the lake, make observations on shoreline development, and track lake activity. The observations made serve as important qualitative indicators of lake health and notes the weather conditions, water clarity, boating traffic, wildlife activity, human activity, and shoreline activity.
