Salmon Falls Watershed

Horn Pond

This 227 acre lake lies south of Great East Lake and west of Wilson Lake with a small 1.8 square mile watershed. Horn Pond is fed by both springs and a few small streams, such as Horse Brook. The lake drains into the Salmon Falls River which forms a natural border between Maine and New Hampshire. The water quality of Horn Pond is considered to be good by Maine standards of clarity and nutrient levels and potentially non-supporting by NH standards based on the median nutrient levels. The potential for nuisance algal blooms on Horn Pond is low. Water flushes through Horn Pond 8.2 times/year, much more frequently than the average Maine or New Hampshire lake which flushes 1 to 1.5 times per year.

For more information, check out the Horn Pond Association’s website or the Horn Pond Watershed brochure. For the most recent water quality report please follow this link to the UNH Lakes Lay Monitoring Program Reports.
