Spencer Lake is a 78-acre impoundment in Medina County, Ohio, located within the 618-acre Spencer Lake Wildlife Area. The lake features two distinctive dam structures - one at each end - due to its unusual location on a watershed divide or "saddle." Originally created in 1961 and expanded in 1970, the lake reaches depths of up to 12 feet in areas that were recontoured along the causeway during a 1985 rehabilitation project.

Boat launching ramps are available on both sides of the lake at the ends of the access roads. While motorized watercraft are permitted, they must operate at idle speed only and cannot create a wake. The lake's relatively protected setting within the wildlife area helps minimize wind exposure for paddlers.

The shoreline environment includes fallen trees, tree stumps, and weed beds that create interesting paddling features while also providing productive fishing habitat. Paddlers can observe various wildlife, particularly during spring migration when waterfowl and songbirds are abundant. Common wildlife sightings include wood ducks, Canada geese, blue-winged teal, and mallards.

The lake is situated in gently rolling topography typical of Ohio's glaciated region. Lower-lying areas around the lake tend to be wet during spring months, which may affect shore access. The surrounding wildlife area includes a mix of crop fields, shrubby coverts, grasslands, and woods that create an attractive backdrop for paddling.

While no specific paddle routes are documented, the lake's modest size makes it suitable for casual exploration. The lake supports a healthy fishery of largemouth bass, bluegill, and channel catfish, making it an excellent destination for paddle-anglers. The water quality is actively managed, as demonstrated by the 1985 rehabilitation project that improved the lake's habitat and fishing opportunities.
