Quapaw Nation Bison Deaths Lead to 63 Felony Animal Cruelty Charges
Quapaw Nation Bison Deaths Lead to 63 Felony Animal Cruelty Charges Against Former Ranch Manager
The Quapaw Nation bison deaths have resulted in 63 felony animal cruelty charges against a former ranch manager following an investigation into the deaths of 32 bison during an extreme August heatwave in northeastern Oklahoma. Brady Kropp, 27, the former manager of the Quapaw Nation Bison Ranch, was formally charged on October 28, 2026, in Quapaw Nation Tribal Court after investigators alleged that the herd went without adequate drinking water for several days.
The charges followed a multi-month investigation by the Quapaw Nation Marshals Service, which examined conditions at the ranch after dozens of animals died or required emergency veterinary treatment for dehydration. Among the animals lost was Frosty, a rare white bison with cultural significance to the tribal community. Investigators allege that Kropp failed to recognize and address the water shortage despite visiting the pasture multiple times. The allegations have not been proven in court, and Kropp is scheduled to appear in tribal court on December 17, 2026.
Quapaw Nation Bison Deaths Result in 63 Felony Animal Cruelty Charges
According to tribal court records, Kropp faces 63 felony counts of animal cruelty, with individual charges corresponding to the 32 bison that died and 31 surviving animals that required emergency veterinary treatment.
Under the applicable tribal law, each felony count carries a potential penalty of up to two years in prison, a $1,500 fine, or both. Those penalties represent the maximum authorized punishment for each count and do not establish what sentence, if any, Kropp could ultimately receive.
A summons was issued when the charges were filed, and the public court docket lists Kropp's scheduled appearance for December 17 at 10 a.m. The case remains pending before the tribal court.
The Quapaw Nation Marshals Service conducted the investigation into the circumstances surrounding the herd's water supply and the actions of those responsible for monitoring the animals. Information about the tribal government and its departments is available through the Quapaw Nation's official website.
The criminal allegations center on whether Kropp failed to provide necessary care and oversight during a period of extreme heat. Investigators have not alleged that he personally shut off the water pumps supplying the pasture.
Investigation Finds Water Supply Interrupted During Extreme August Heat
According to the probable cause affidavit, pumps supplying a 700-gallon watering tank connected to a water tower maintained by Downstream were turned off on August 18, 2026.
Investigators estimated that the tank could have emptied within approximately 24 hours because bison require substantial quantities of drinking water, particularly during periods of extreme heat. Officials estimated that an individual bison consumes approximately 15 gallons of water daily, although actual needs vary with temperature, animal size and other conditions.
The water shortage occurred during exceptionally hot and dry weather. Investigators reported that August high temperatures in the area averaged approximately 99 degrees, while recorded rainfall totaled just 0.02 inches. Two ponds within the pasture had also reportedly dried up, eliminating additional sources of drinking water for the herd.
The National Weather Service Tulsa office provides weather observations and climate information for northeastern Oklahoma, where prolonged heat and limited rainfall can place additional stress on livestock and agricultural operations.
Investigators allege that Kropp visited the pasture multiple times during the following eight days without identifying the empty watering tank or the dry ponds. According to the affidavit, he discovered the lack of water on August 26, arranged for a water truck and notified the tribe's agriculture director after finding a dead bison.
The resulting losses included 26 heifers, five calves and one mature bull. An additional 31 bison survived but required emergency veterinary treatment for dehydration.
Among the animals that died was Frosty, a rare, genetically pure white bison that held cultural significance and was well-known within the Quapaw community. The animal's death drew particular attention to the tragedy because of its importance beyond the ranch's agricultural operations.
Quapaw Nation Implements New Safeguards Following Herd Losses
Following the deaths, the Quapaw Nation announced operational changes intended to prevent similar emergencies and strengthen oversight of its remaining bison.
The tribe reported that the loss represented approximately 18% of its herd, leaving 143 surviving bison. Officials have since implemented more frequent inspections and additional documentation requirements for staff responsible for animal care.
Under the revised procedures, ranch personnel must conduct twice-daily herd checks and complete daily monitoring records to document animal conditions and identify potential problems with water availability or other essential resources.
The tribe is also developing a new water well, expanding the capacity of pasture ponds and installing additional watering equipment. Those improvements are intended to create more reliable water sources and reduce the risk of a single equipment failure affecting the entire herd.
Adequate water access is particularly important for large grazing animals during prolonged periods of high temperatures. The USDA Natural Resources Conservation Service provides agricultural conservation resources addressing livestock water systems, grazing management and infrastructure designed to support healthy herds.
The Quapaw Nation's new safeguards reflect an effort to improve monitoring, establish additional water sources and protect the animals remaining at the ranch while the criminal case proceeds through tribal court.
The Quapaw Nation bison deaths have led to 63 felony animal cruelty charges against former ranch manager Brady Kropp, with prosecutors alleging that failures in herd monitoring contributed to the deaths of 32 animals during extreme August heat. As Kropp awaits his December 17 court appearance, the Quapaw Nation is implementing additional inspections and water infrastructure improvements to protect its remaining bison and prevent another devastating loss.
