This area supports the only stable population of the Hungerford's crawling water beetle, recording nearly 1052 beetles when last counted in 2002. This area is largely within and along the boundary of the

Hungerford's crawling water beetle is more or less ovoid, with a markedly convex upperside. They have a yellowish-brown color with irregular dark markings. They are extremely small (3.8–4.3 millimetres or 0.15–0.17 inches long) which may contribute to the difficulty in locating them. Their

The Carp Lake River and Van Hetton Creek identifications were significant as they represented a new location beyond those originally identified when the
Hungerford's crawling water beetle was categorized as endangered in 1994. This suggests that the rare beetle may occur in other sites as yet
327:, two adult beetles were found in surveys in 1989 and again in 1996 two more adults were found. Still, the status of the population there remains uncertain. In July 1999, six additional adult beetles were identified elsewhere in the Mackinaw State Forest in Van Hetton Creek.

as well as parts of its hindlegs. These hindleg plates do not move although they are not fused to the beetle's centerline. As with all
Haliplidae, these specialized hindleg plates function as air storage devices supplementing the air carried under the wing covers.

It is believed that the
Hungerford's crawling water beetle requires cool (15–25 °C or 59–77 °F), swift flowing alkaline streams with sand and gravel bottoms. While in their larval stage, the beetles gather in concentrations of

Although most other
Haliplidae are capable of flight, only one observation of a flying Hungerford's crawling water beetle has been made. It is not certain how far adults fly or what triggers them to initiate flight.
