Harveys Lake (also known as Harvey Lake or Harvey's Lake[1]) is a natural lake in Luzerne County, Pennsylvania. It has a surface area of approximately 621.5 acres, or nearly a square mile. The lake is situated entirely within the borough of Harveys Lake.[2][3] 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. Various species of fish inhabit the lake and a number of bird species have been observed in its vicinity.
Harveys Lake was accidentally discovered by Benjamin Harvey in 1781. The first settlers arrived at the lake in the 1790s and 1800s. Early industries in the area included lumbering and farming, but it became well known as a summer resort in the latter part of the 1800s and into the 1900s. It was also used as a water supply in the early 1900s. However, the lake began to develop significant environmental problems in the 1960s and a total maximum daily load was created for it in 1994. Since 1968, the lake has been located in the borough of Harveys Lake.
