Harveys Lake is situated in the United States Geological Survey quadrangles of Harveys Lake and Noxen.
The watershed of the lake has an area of  3,600 acres (1,500 ha).
Most of the watershed is in Luzerne County, but its northeasternmost portion is in Wyoming County.

The vast majority (2,841 acres [1,150 ha]) of the watershed of Harveys Lake is forested land.
Developed land and farmland comprise 499 acres (202 ha) and 154.7 acres (62.6 ha), respectively.
Unpaved roads make up 2.5 acres (1.0 ha) of the watershed.
The majority of the developed land in the watershed is directly on the shoreline and nearly all is within 0.5 miles (0.80 km) of the lake.
Most of the developed land is used for residential and commercial purposes.
One developed area in the watershed is known as Hemlock Gardens, which occupies an area of 28 acres (11 ha) and has 26 homes.
The development had steep slopes (8 to 18 percent grade), unpaved roads, and no infrastructure for dealing with stormwater.
However, a nutrient-separating baffle box and a water polishing unit were installed in the development, reducing the phosphorus load of Harveys Lake by an estimated 36 pounds (16 kg) per year.

The shoreline of Harveys Lake is entirely surrounded by a paved road, which is atypical for a lake shoreline.
Homes and cottages are situated on the road opposite the lake, and significant development has occurred in the vicinity of the lake.
A ditch and outlet drainage structure made of concrete at Wardens Place drains into the lake; its purpose is to control small-scale local road flooding.
