It’s not the 455-acre lake that makes Yellowstone Lake State Park special. It’s not the 4,050 acres of adjoining wildlife habitat and cropland either.

What makes Yellowstone Lake unique is the lack of mosquitoes and a glossy-eyed mammal with wings.

The 968-acre park is the summer home to more than 4,000 little brown bats. The bats roost in 31 bat houses throughout the park. The houses serve as nurseries, where the bats raise their pups.

The project is the work of Kent Borcherding, a park volunteer from Hazel Green, who has maintained the houses and been working with the bats since 1995. Borcherding also gives interpretative presentations on the bats.

Each evening campers gather around the bat houses to watch the bats flit about the sky on their hunting expeditions. Since each bat can catch up to 600 mosquitoes an hour, they have nearly eliminated the mosquito population. This benefit is greatly appreciated by campers!

The bats have quickly become a highlight to the park’s interpretive program. In 2000 Merlin Tuttle, founder of Bat Conservation International in Austin, Texas, brought a film crew to Yellowstone Lake to film the little brown bat. BCI used the documentary for promotion and to inform the public that bats aren’t the hazard most people believe they are. In fact, even with the high concentration of bats in the park, there has never been a human/bat conflict. --Nicole Perrault, park naturalist

Water Recreation

While the bats provide evening entertainment, the lake furnishes the bulk of day activities. The 455-acre lake is shared by personal watercraft, boats, kayaks, canoes, swimmers, and anglers.

Since 1997, 400,000 pounds of carp were taken from Yellowstone Lake. The lake has become clearer and has an abundant population of crappies and walleye, and the game fish populations are flourishing. Fishing opportunities also exist for bass, bluegill, channel catfish, muskies and northerns. Department of Natural Resources fisheries biologist Bradd Sims coordinates the carp removal.

From 1997 to 2000, Yellowstone Lake was catch-and-release-only on game fish. The lake is now open to fishing with the following regulations: Yellowstone Lake (including the Yellowstone River from the lake upstream to County Highway F):

• Walleye, sauger, their hybrids, and channel and flathead catfish between 15 and 18 inches, and largemouth and smallmouth bass between 12 and 15& inches, may be kept with a total daily bag limit of two fish.
• Catch and release only on northern pike, muskellunge, their hybrids, gar and bowfin.

Camping

The park offers 128 individual campsites; 108 are reservable and 38 have electrical hookups. The east side is open year-round and has 36 campsites, and the west side is open from May to October and has 93 campsites.

There also are five reservable groups sites, four with electricity.
