The roughly heart-shaped lake is immediately to the southwest of downtown Carmel. Its 168 acres (68 ha) are surrounded by grassy parkland sloping down to the lake from the roads on the south and east, and woods on the other sides. NY 301 follows the north shore, ascending to its eastern terminus at NY 52 across from the Putnam County courthouse. Route 52 follows the eastern shore for a short distance to the south of this intersection before it, too, ends at US 6, which continues around the southern shore. There is no road along the western side, although a local street, Glenvue Drive, traverses the top of the 545-foot (166 m)-high ridge there.
The lake fills a small depression in the middle of a hilly area. Its bottom continues its rapid drop from the shoreline, reaching a depth of slightly over 100 feet (30 m) in the middle of the lake, equivalent to the surface of a swampy depression to its east. Mean depth is 48 feet (15 m). It typically contains 8.042 acre feet (9,920 m3), or 2.6 billion US gallons (9,800,000 m3) of water.
There are no inlet brooks, as the lake was originally a pond. A small, unnamed outlet brook drains from the northwest, emptying in less than a thousand feet (300 m) to West Branch Reservoir. Water not impounded and delivered to the city from there follows the Croton River to the Hudson.
The lake was originally known as Shaw's Pond, after an early landowner. It had been a part of the Carmel landscape since the hamlet's designation as county seat upon Putnam's 1814 creation. It quickly became a popular spot for boating and fishing.
The name started appearing on maps around 1840. Not long after, residents became dissatisfied with the name and proposed grander names for it. In 1852, a committee of local residents finally settled on Lake Gleneida. Eighteen years later, in 1870, New York City bought the lake and dammed it, bringing it to its present size and volume.
The New York City Department of Environmental Protection (DEP) owns Lake Gleneida, considered one of three "controlled lakes" in the city's water system. That means it may withdraw water as a right of ownership.
Recreational use of the lake does come under DEP regulations. Fishing, ice fishing and boating are allowed with a valid DEP permit and New York State Department of Environmental Conservation-issued fishing license. Swimming is not permitted.
Boats used in the lake may not be used in any other body of water, to prevent the spread of zebra mussels. This raised some local concern in 2005, since many were left on shore during the offseason and the town found them unsightly as it prepared to spend $2.3 million to spruce up the hamlet. DEP was able to get most of the owners to relocate them to storage areas out of sight of downtown.

"The lake, along which the village lies, was formerly called Shaw's Pond. It was a beautiful lake, and afforded excellent fishing and boating. But there was something wrong about it. Finally the citizens concluded that the trouble lay in the name. A meeting was called and a committee was chosen to select a name which would do justice to this beautiful sheet of water. The committee finally hit upon "Lake Gleneida" and this was at once applied to it."
