Current Numbers: 4
Pack Status: Active. Designated in October 2011.
The Snake River Pack was discovered in October 2011 in NE Oregon. They had at least three pups in 2012. By the end of 2012, seven members of the pack were reported, including OR-15, a collared pup.
nine by the end of 2013. By the end of 2014, there was a breeding pair and at least four pups observed, and at least three pups observed in 2015. In 2014, OR-18 was collared during a helicopter capture operation. He was estimated to be just shy of two years old. OR-18 appeared to be dispersing to the West, but was unable to cross I-84. After turning around, he headed east before being illegally killed in Montana.
In 2014, OR-24 dispersed from his Snake River Pack when he was two years old and paired up with OR-27, a disperser from the Minam Pack. They became known as the Catherine Pair, and then were designated pack status and became the breeding pair of the Catherine Pack.
In 2016, 2017, and 2018, the pair produced at least three pups each year that survived to the end of the year.
Unfortunately, although the pack produced pups in 2019, no pups were found during the 2019-2020 winter survey, so the pack’s official status was revoked.
In 2025, new resident wolf activity was documented in the Snake River unit. Breeding for the first time, a new pair produced at least two pups that survived until the end of 2025. Four total wolves were documented in the new Snake River Pack during the winter count.
