Chocorua Lake is very shallow, with an average depth of 12 feet and a maximum depth of 27 feet. As a result, sunlight reaches through most of the water column. Thus, even low concentrations of nutrients are readily available to algae and other plant life that occur throughout the lake.
Thanks to the efforts of the Chocorua Lake Conservancy, about 95% of the Chocorua Lake watershed is now protected through conservation covenants and easements which have preserved wooded buffers around the lake.
In the early 1970s, the Conservancy persuaded the NH State Legislature to ban all motorboats from Chocorua Lake and successfully defended that ban again in 1998.
Since 1978, the Conservancy has been tracking the water quality in Chocorua Lake in a partnership with the UNH Center for Freshwater Biology.
In 2001, the Conservancy was awarded a “Conservation Award of the Year” by the Carroll County Conservation District for our work on the “Berms & Swales” project, which resulted in a 92% reduction in phosphorus runoff into the lake.
