Montana Fish, Wildlife and Parks (FWP) has observed a significant decrease in the fish population in the Stillwater River over recent years.
FWP attributes this decline to a combination of historic flooding two years ago and subsequent cleanup efforts, with human activities possibly playing a role as well, according to FWP fisheries biologist Bryan Giordano.
The report focuses on two sections of the river: the upper portion above Rosebud Creek and the lower portion below Rosebud Creek, both experiencing declines in fish population that are concerning to FWP.
The upper portion has seen a gradual decline over the past two decades, resulting in 10% fewer fish due to reduced water flow. The lower portion, on the other hand, witnessed a drastic 50% decrease in fish population from fall 2022 to fall 2023.
Local businesses and recreational activities, such as angling, are impacted by the declining fish population, as highlighted by 90-year-old Bob Kimball who runs a fly shop in Absarokee and emphasizes the importance of natural resources and fishing.
Kimball encourages anglers to be mindful of the population decrease and play a role in conservation efforts. FWP suggests that habitat loss as a result of flood cleanup is a major factor contributing to the decline, and is seeking assistance from landowners along the Stillwater River to help rebuild fish habitats along the shoreline.
“We’re looking for willing landowners to participate in fish-friendly projects to support the rebuild,” Giordano stated. “Any help with rebuilding habitats would be greatly appreciated.”
