A dam at the lake’s outlet is used to control water levels. The lake has a surface area of approximately 2,072 acres, a maximum depth of about 56 feet, a volume of approximately 44,800 acre-feet, and a mean depth of about 21 feet.

This lake supports excellent populations of walleyes, northern pike and largemouth bass. Estimates are a total of 11,800 adult walleyes, or 5.7 per acre, which is excellent for stocked lakes. These walleyes are in excellent condition and many are larger than the 18-inch minimum size limit. There are also estimates of 4,970 adult northern pike, or 2.4 per acre, which is very good and representative of healthy naturally reproducing populations.

Smallmouth bass aren’t quite as abundant but size structure is excellent. Smallmouth average 16 inches, with some sampled fish up to 19 inches.

Samples of muskies were found up to 48 inches, although there were not abundant. The lake has plenty of bluegills, with the average size six inches but also fish eight inches and larger.
