Harveys Lake (also known as Harvey Lake or Harvey's Lake) is a natural lake in Luzerne County, Pennsylvania. It has a surface area of approximately 621.5 acres (251.5 ha), or nearly a square mile. The lake is situated entirely within the borough of Harveys Lake. By volume, it is the largest natural lake in Pennsylvania, and by surface area, is the second-largest lake. It is a glacial lake surrounded by hills and is the source of Harveys Creek, a tributary of the Susquehanna River. The lake has a stone masonry dam. The lake's watershed has an area of approximately 3600 acres. The majority of the watershed is forested, but there is some developed land as well. Nearly all of the developed land is close to the lake itself, and the lake is surrounded entirely by a paved road. Harveys Lake was affected by algae blooms from the mid-20th century onward, and these algae blooms were caused by pollution of nutrients, especially phosphorus. The lake was identified as impaired in 1994, with an annual phosphorus load of 1,019 pounds (462 kg). However, the phosphorus load has been reduced somewhat since then. The lake is listed on the Luzerne County Natural Areas Inventory. A number of rare or endangered plant species have been observed in its vicinity.
