Lake Little Sissabagama is the product of the last great glacial age that swept through the upper Midwest called the Wisconsin Glaciations. It occurred at the end of the Pleistocene Epoch period, between 75,000 to 10,000 years ago, leaving the area around Hayward and Spooner with knobby and kettle topography known as Hummocky. The area also has varied ridge formations known as moraines. Lake Little Sissabagamas' formation was likely the result of large, stranded, detached blocks of melting ice that were buried under sand and gravel trapped by moraine hills. As the ice melted it collapsed, leaving crater-like depressions, which filled with water over the centuries. One of the best ways to view the glacial topography of the area is to hike the Wisconsin Ice Age Trail, which passes very near Lake Little Sissabagama.
The area near and around the lake is heavily wooded with a variety of trees, ferns, flowers, bushes and grasses. A large number of lakes and marshes in the area provide for a diverse collection of plants. Trees in the area range from a broad variety of Pines to Birch, Oak, Maples, Ash and Butternuts and Tamarack. A wide variety of fungus is also prevalent as are moss and water plants.
The lake area is host to: Loons, geese, grouse, ducks, deer, wolves, coyote, chipmunks, squirrels, rabbits, bear, beavers, otters, muskrat, fishers, weasels, raccoons, turtles, frogs, mud puppies, snakes, and the occasional moose. The lake fish population consists of musky, bass, crappie, northern, bluegill and sunfish. Although the occasional walleye has been said to be caught in the lake, the structure of the lake is not suitable for walleye breeding. Northern pike are new to the lake since 2004 and though to have migrated the old canal ways from Big Sissabagama during spring flooding or were introduced by human interference to one of the lower lakes connecting to Little Siss.
The Secchi Disc readings (visibility of water) average 13 feet to 17 feet depending on the time of year and water clarity is considered above average. The lake bottom is comprised of 50% sand, 40% gravel, 10% bedrock and soil / decay matter. The lake depth is an average of 35 feet with the deepest section measuring 75 feet. Sections of the lake are bordered by marsh to the North and high, heavily forested ridges and hills to the South, East and West.
Several streams, small lakes and underground springs, feed the lake. Most of the lakes surface water is replenished by winter snow and annual rain. The lake is subject to moderate water level changes of 7 to 14 inches. The lowest levels occur in the late fall.
Cabins on the lake are well camouflaged with heavy tree cover. The lake has large tracks of private undeveloped property and protected tracks of land on association property and DNR property making it an ideal lake for hiking, x-c skiing, boating, swimming and general recreation. There are no farmlands that intrude on the lake waters or streams that enter the lake. The lake has no public boat landings. The only public access is through Boulder Lodge.
The lake is approximately 300 acres in size and comprised of numerous islands, bays and peninsulas. The lake is 1.42 miles long and .7 miles wide.
