Local Flora and Fauna
Our lakes are located in the unique ecotone transition zone between the warmer deciduous forests to the south and the cooler coniferous forests to the north. Scientists measure the northward extent of the range that southern deciduous forest species thrive, and the southern extent of the range that northern coniferous forest species survive. Where those ranges meet is called the transition zone and an unusually high number of plant and animals species can be found there. 67 different species reach their maximum range in Polk County where the northern and southern ranges meet. Northern plants and animals found commonly here, will not be found just a few miles to the south and visa versa. The dominant native trees in the area are northern red oak, white oak, ash, white pine, paper birch and sugar maple. Common shrubs include hazel, dogwood, pin cherry and blackberry. Water plants like bulrushes, cattails, water lily, American lotus, arrowhead and blue flag iris line the lakeshores. Under the water you’ll find coontail, pondweed, northern milfoil and water celery.

Fishing
Anglers will find a lot of fishing action out on the water of all three lakes in any season. These lakes are most noted for their consistent pan fish production, largemouth bass action, the occasional whopper, and can generally provide a fun filled outing that equals any of the big fisheries in the area. The lakes have been tested for toxic levels of mercury, but no consumption advisories have been issued. Most people fish in the summer from a boat, but many folks try their luck in the winter too. Fish houses appear on the ice soon after freeze up, and folks scurry from hole to hole checking for bites. One has to be careful while walking out on the ice not to step into any unattended fishing holes. In the warmer months, fishermen are usually the first ones out on the water in the morning staking their hot spots, and the last ones to go home at night. Although serious fishermen with their depth finders, underwater cameras and scented lures might be trying to land one just a little bit harder than the kids on the dock using bamboo poles and corn for bait, they often seem just as successful. The annual game fishing opener is the first Saturday in May. Residents and non-residents 16 and over must carry a license to fish. One of the busiest fishing weekends is the annual free fishing weekend, held the first weekend in June each year. No license is required and it’s a perfect opportunity for anybody to wet a line. On this weekend you’ll often see boats loaded to the life jacket limit with eager anglers hoping to catch their first fish. Fresh fishing bait is available at the Big Lake Store.
The most sought after fish in the lakes are:
- Walleye
- Northern Pike
- Largemouth Bass
- Perch
- Crappie
- Bluegill Sunfish
- Pumpkinseed Sunfish
- Green Sunfish
Mammals

Common and sometimes a pest. To avoid contact with people, they browse on woody twigs and grasses from early evening, through the night until morning. They especially love tulips in the spring and white oak acorns in the fall, and anything tasty you want to grow in your garden. You may want to protect your young trees until they grow beyond the reach of hungry deer.

An occasional visitor. Bears are mainly vegetarians, very curious, shy, and easily scared off by loud noises. Given the opportunity, a hungry bear in the springtime will destroy your birdfeeder.

A very persistent and bold nighttime raider that will eat just about anything. Often traveling in family groups.

Bats use high frequency echolocation to navigate and locate insects. A bat scoops insects into its tail membrane and transfers them to its mouth all in the blink of an eye. A bat can eat half it’s weight in mosquitoes every night.

Very territorial with home ranges about the size of a city block. Grey Squirrels prefer deciduous trees over conifers.

Very territorial with home ranges about the size of a city block. Red squirrels prefer conifer trees. These squirrels often bite off cone bearing branches and then come down to the ground to collect the cones.

Two species of chipmunks inhabit our area. Eastern chipmunks have black and white stripes only on their backs. Least chipmunks have similar stripes, but also on their tails. They search the forest floor for seeds and nuts to store for the winter. They live in burrows or woodpiles, and eat mainly fruit in the summer.

An occasional visitor. Often seen in winter lying on an elevated woodland perch on the lookout for a potential meal.

A woodchuck is a large ground squirrel that makes its home underground in burrows, sometimes under your house. They hibernate for seven months of the year.

Very common, very prolific, and are known for eating anything green in the winter above the snow. Woody shrubs, twigs, grasses, small trees and saplings are favorite foods.

Inquisitive, ferocious and elusive predators that are always on the move, running along the shoreline investigating every crevice, looking for an easy meal.

A furry rodent with a rat like tail that swims in the lake. Always found near cattails, which it uses for food and to make its home. The population has a 10 year cycle so you may see many one year and few or none the next. They really do eat themselves out of house and home to the point where they starve to death. Muskrats love to chew on exposed wiring on any watercraft, often causing expensive boat repairs.

This animal hunts small rodents mainly by scent and sound. Often sits upright to observe greater distances.













Birds
The bird watching on the lakes and throughout the area is exceptional. A large number of interesting species are year round residents. Sparrows, dark eyed juncos, black capped chickadees, nuthatches, northern cardinals, doves, house wrens, crows and downy, hairy and pileated woodpeckers are very common and can be found all winter long. Summer residents include various finches, grosbeaks, warblers and thrushes. Look for bluebirds, red winged blackbirds, robins, blue jays, grackles, belted kingfishers and tree swallows by the lakeshore.
In the springtime, as the insects hatch, the migrations begin. The warmer southerly winds bring migrations of dozens of bird species that are just passing through, and others that come to stay just for the summer. Most summer songbird visitors eat insects exclusively. The lakes attract water birds of all kinds that arrive just as the ice goes out. Herons, Canada geese, egrets, kingfishers, various ducks, coots, mergansers, swans, loons and cormorants have all been observed regularly passing through, and sometimes staying on for the summer. As spring progresses, newly arriving songbirds begin staking their territories, singing their songs, seeking mates and building nests.
Larger birds of prey like bald eagles and red tailed hawks are also common. Soaring eagles can spot a fish in the water from a mile away, and can carry away up to five pounds of fish at a time. Owls do most everything in the dark and can be heard year round making some of the most outrageous nighttime hoots, wails and shrieks. Listen for the gobble of wild tom turkeys gathering their flocks early in the mornings. Look for waves of tiny tame golden kinglets arriving on warm, moist spring mornings, searching for newly hatched insects. Stick out your finger and they’ll land on it. Watch out for swallows building mud nests on steep banks along the shore, sometimes even under the bridge. Ruby throated hummingbirds and northern orioles readily visit nectar feeders. Bright yellow goldfinches travel in small flocks and seek ripe seeds, not insects.
The fall migration for some species really begins in July as soon as the nesting season is over, and picks up in intensity as the days grow shorter. The gulls that flock on the lake late each summer are actually on their way south, after nesting in the arctic. Most songbirds stop singing by mid July, and are gone by mid to late September. After the first freeze the insects are gone and birds move south on cool northerly winds. The lake usually freezes over in late November or early December, chasing away the last of the water birds and bringing an end to the birding season.
Reptiles

Can be found on all three lakes, especially sunning themselves on logs and water plants in the warm sunshine.

Snappers can grow to be quite large, up to 75 lbs. You can often see them sticking their heads out of the water for a breath of fresh air and to have a look around. They’re docile in the water, but will lunge at you with jaws wide open on land. Their sharp jaws can deliver a painful bite. Once bitten, they often won’t let go. Turtles can only lunge forward so a quick step to the side will protect you from a bite.

This familiar snake is non-poisonous and harmless. The snake has a dark body with three yellow stripes. It can grow up to 2 feet in length, and seeks out insects, worms, frogs and mice for its meals.



Amphibians

These leaping green frogs with black spots can be found in any moist area, especially near the lakeshore. They begin to sing when the water temperature reaches 68 degrees.

Measuring only 1-¼ inches from nose to tip, these frogs are the first to emerge in late March. The call is like the sound of running your finger over a comb.

Found in marshes or wetlands away from the lakes. These frogs have toe pads that allow them to climb vertical surfaces.

These frogs begin to breed in small ponds in late March or early April, as soon as the water’s edge is ice-free. You can often find these frogs with their “robber’s mask” hiding in your garden looking for insects. Most frogs over winter under the lake ice, but wood frogs can freeze solid in the winter and then miraculously regenerate in the spring.

Different species can only be detected by the variations in their songs. As the temperature rises, the tiny green or grayish frogs become bright green and are very hard to spot in the vegetation.

These toads are usually brown, but sometimes reddish in color, and often have warts on their backs. They live in forests, prairies and near lakeshores.

Green frogs spend their days hidden in cool grasses by the water’s edge. Beginning in June, at nighttime they begin to “croak” loudly.







Insects and other Invertibrates

Mayflies begin hatching from the water in early spring. Given the right conditions, the sheer numbers of bugs with clear wings and two long tails trailing behind them can be astounding. The first hatch is the biggest and most noticed, but the flies don’t all have their timing right and are actually hatching in smaller numbers most of the early summer. Mayflies are an indicator species of the quality of habitat, and their presence confirms that our lakes are in good health. After growing underwater for six to eight years, their above water life lasts only two days. They use chemical signals to locate a mate while flying above the water. The females then touch the water surface depositing up to 1000 eggs that sink down to the lake bottom and start the life cycle over again. Many fall into the water and the fish come to the surface to feast.

These large carnivorous flies search with big eyes, composed of thousands of facets, helping to detect the movement of any nearby bug. They fly up to 30 miles per hour and can stop, back up, and then zip off again. There are mainly four different kinds in this area and they do not bite. Darners show flashy metallic blue and green colors in the bright sunshine.

Look for beetles in quiet water in spring and fall, usually close to the water surface. They lay their antennae on the surface to detect any nearby ripples that may be a potential meal. Their four back legs act as paddles leaving their front legs free to catch anything within reach.

These oblong shaped beetles use light signals like a code of love. Males flash green, yellow or orange while flying and the females flash from the same place hoping that handsome stops by.

These yellow butterflies with tiger like black stripes hatch out of their cocoons in June. Their body temperatures must reach 82 degrees for them to fly properly and in control. Females lay their eggs on birch, cherry and ash trees leaves and then ten days later tiny green caterpillars emerge and begin eating the leaves.

During the day the large insect is out of sight, backed into the sand or a crevice among the rocks on the shore. At night it comes out looking for algae found along the rocks and plants. It is a favorite food of herons and fish.






Nuisance Critters and Plants

Wood ticks and deer ticks are common in this area. Check and re-check yourself if you have been in likely tick areas. Deer ticks may carry Lyme disease, an illness that may affect the skin, joints, heart and nervous system.

Biting mosquitoes can carry blood borne diseases, including West Nile. Use insect repellant or cover your skin to protect yourself.

Biting deer flies often circle your head before they attack. Wear a hat sprayed with insect repellant or stand in bright sunshine.

These ¾ inch long insects are usually ankle biters or a full-scale menace if you’re lying out on the ground. Like mosquitoes and deer flies, only the female bites.

These are tiny flies, often found in swarms. They use four sharp teeth to slash the skin.

A woody vine with three leaves often attached to trees or found on the forest floor. Oils in the plant contain a powerful toxic skin irritant. “Leaves of three, let it be.”

A wetland or lakeshore plant with a spike of beautiful purple flowers in the late summer. This hardy plant grows up to eight feet tall, crowds out native vegetation and is highly invasive. Dig out and destroy this plant before it goes to seed.

A fast growing waterweed that forms thick mats on the water surface, making the lake unattractive to fish, wildlife and humans. Always inspect your boat and trailer, and remove any weed fragments that could be transported to or from another body of water.
