Cunningham Falls State Park has restricted access to its lake following two separate incidents where visitors were bitten by rabid beavers.
Management at Cunningham Falls State Park in Frederick County, Maryland, has taken decisive action to protect the public following a series of alarming encounters involving wildlife. The park has officially restricted access to the day-use areas surrounding Hunting Creek Lake. This decision stems from two separate, unprovoked attacks off-limits to swimmers and visitors, the broader areas of the park, including hiking trails and designated camping grounds, remain operational for public use.
According to officials from the Maryland Department of Natural Resources, the closures will remain in effect until wildlife biologists and park management can guarantee the area is free of further threats. To ensure the safety of the public, authorities have deployed a multi-faceted monitoring strategy. This includes the strategic placement of traps, as well as the use of specialized thermal imaging equipment during nighttime surveys to identify any remaining animals in the vicinity. Park staff continue to monitor the shoreline and surrounding vegetation for signs of beaver activity, maintaining a heightened state of vigilance throughout the property.
The first incident involved a teenage boy who suffered significant injuries to his chest and hands during an encounter with a beaver. The severity of the wounds necessitated an emergency medical response, and the victim was airlifted to Johns Hopkins Hospital for specialized treatment. Shortly after the attack, the animal was euthanized, and laboratory testing confirmed it was infected with rabies. This initial event served as a catalyst for the immediate closure of swimming areas within the lake.
A second incident occurred on August 5, involving a 19-year-old fisherman who was bitten on the ankle. The victim sought medical attention, which included a tetanus shot and a thorough assessment for potential rabies exposure. As with the first incident, the beaver was euthanized and subsequently confirmed to be rabid. These repeated events have highlighted the necessity for the ongoing restrictions at the popular destination, which saw over 455,000 visitors during the 2025 season.
Medical experts emphasize that rabies is a serious, potentially fatal viral disease transmitted through the saliva of an infected animal, typically via bites or scratches. While rabies in domestic dogs has been largely controlled in the United States, the virus remains prevalent in wild populations. Beavers, which are naturally skittish and typically avoid human contact, undergo significant behavioral shifts when infected. The virus impacts the central nervous system, often leading to a loss of fear, extreme aggression, and a state of disorientation.
Observers should be aware of specific warning signs that indicate an animal may be compromised. These include abnormal coordination, excessive salivation, and uncharacteristic vocalizations. Because rabies can disrupt an animal's natural circadian rhythms, nocturnal creatures may be seen behaving erratically during daylight hours. Experts warn that any wild animal displaying such uncharacteristic behavior should be treated as a potential health hazard and avoided at all costs.
In the event of an animal bite or scratch, immediate medical intervention is critical. Victims are advised to move away from the animal to prevent further injury and to thoroughly cleanse the wound with soap and water for at least 10 to 15 minutes. Once the immediate area is safe, the individual should seek professional medical care, where doctors may initiate a series of rabies vaccinations. It is vital to note that rabies is fatal if left untreated, making timely medical consultation non-negotiable.
Furthermore, authorities strongly discourage members of the public from attempting to capture or interact with suspicious wildlife. If an animal appears sick or behaves aggressively, the public should prioritize their own safety ies. , visitors can help prevent further incidents while experts work to manage the situation at the lake.
