A watershed survey of the Depot Pond and a soil erosion reduction project at the Milton Town Beach were completed in 2010, as part of a comprehensive watershed-based Lake Management Plan for the Milton Three Ponds of Milton NH and Lebanon ME. The watershed survey was accomplished by Three Ponds Protective Association (TPPA) member volunteers assisted by professionals. The professionals served as surveyor trainers, survey team leaders, and technical reviewers. The soil erosion project was accomplished as a pilot Lake Conservation Corps (LCC) project. It consisted of installing three rain gardens, a water retention basin, and two sets of infiltrations steps. Much of the work was done by a team of students from Nute High School.
