Ballantyne Lake encompasses 371 acres with 4 miles of shoreline in Blue Earth County, Minnesota. The lake features a public boat launch, making it accessible for paddlers. The lake's maximum depth reaches 58 feet, creating varied paddling environments from shallow nearshore areas to deeper open water.

Located along the scenic Sakatah Trail, Ballantyne Lake is part of a chain of lakes including Madison Lake and Duck Lake. The trail, which runs east to west, provides views of all three lakes and offers opportunities to combine paddling with other outdoor activities.

The lake supports a diverse fish population, including northern pike, walleye, largemouth bass, and various panfish species. Paddlers should note the presence of Eurasian watermilfoil, an aquatic invasive species, and follow proper clean-boat protocols when entering and leaving the water.

A 2019 lake survey indicated that Ballantyne Lake maintains a relatively healthy fish community, with 17 native fish species present in nearshore areas. The lake is situated near the communities of Madison Lake, Eagle Lake, and Mankato, offering convenient access to amenities.

Two state parks lie within proximity: Minneopa State Park and Sakatah Lake State Park, providing additional recreational opportunities for paddlers planning extended visits to the area. Several neighboring lakes, including Duck Lake (290 acres) and Madison Lake (1,447 acres), offer possibilities for multi-lake paddling adventures within short driving distances.
