Before the late 1700s, Lake Hopatcong was known by several names, including Great Pond and Little Pond (before flooding into a single lake), Sandhay Sea (circa 1648), Brookland Pond (mid-1700s), and Musconetcong Pond (1769).


Lake formation

that forced water from the basin into the Musconetcong River. The glacier left behind two ponds, nearly apart. In the early 1700s, the Great Pond stretched between Henderson Bay and today's Hopatcong State Park. Little Pond was a small body of water to the south of Woodport. The two lakes were first dammed in 1750. By 1831, Lake Hopatcong had been flooded to nearly its current shape.

of Native Americans.


Colonial development

Colonial exploration of the Great and Little Ponds began in the 1600s. Between 1750 and 1764, a dam was built on the Musconetcong River for the Brookland Forge and mill where the river empties from the lake (now the area of Hopatcong State Park), raising the water level by about and joining the Great and Little Ponds into one. By this time, most of the local Lenape population had died of disease or left the area. In the years that followed the

This new dam raised the water above the original level of Great Pond, and caused the Great Pond to connect with Little Pond and form the current Lake Hopatcong. The flooding and subsequent formation of a single, large lake created a new geography of the area.

21st century


2000 flood

More than of rain fell in a small area of southeastern Sussex and northwestern Morris County in northwestern New Jersey during August 11–14, 2000. Doppler radar estimates of total rainfall for the 4-day period reached about along the border between Sussex and Morris Counties. A severe thunderstorm on August 12 dropped so much rain in six hours that it was judged a 1,000-year event. Peak flows at the USGS gauges on Lake Hopatcong (01455400) and Musconetcong River (01455500), among others, were the highest ever recorded. These gauges are at sites that drain areas that received 10 or more inches of rain during August 11–14. Peak flows on Lake Hopatcong and on the Musconetcong River just downstream from the lake exceeded those of a 100-year flood. Lake Hopatcong sustained flooding damage, particularly the Great Cove area at Nolan's Point.

’s (DEP) water level management plan allows the lake to be lowered to allow for inspection of the dam structure, property owners’ repairs to lakeshore structures, aquatic vegetation control, and silt and drainage material removal from areas around the lake. From December 2008 to January 2009, the DEP left the dam open almost three weeks too long, which caused the water level to drop almost a foot (0.3 m) below the normal drawdown level. A coalition of residents and business owners filed suit against the DEP and the State of New Jersey, as of 2009 it was being appealed in local court. The suit claims that the DEP, against their own policy, carelessly allowed an excess of of water to be released through the dam. On May 11, 2009, the American Power Boat Association (APBA) and the Lake Hopatcong Racing Association (LHRA) decided to postpone their annual races due to the low water level. However, with the large amount of rainfall that was recorded in the month of June, the lake returned to its proper level above the normal average depth. The return of the water level came just in time for the beginning of summer and the arrival of the weather required for boating. In July 2014, there were reports of a
