The Upper Big Hole River is home to the native Arctic grayling. The Upper Big Hole was the last location in the lower 48 states to host a natural producing population of Artic grayling in a river. Grayling historically occupied much up the Upper Missouri to Great Falls, Montana. Changes in habitat resulting from development, large dams and mining beginning in the late 1880’s caused the fish to decline dramatically. In the Big Hole, their decline was exasperated by drought in the 1980’s causing the fish to drop to dangerously low populations.

In 2009, Montana Fish, Wildlife and Parks in partnership with US Fish and Wildlife Service, Montana Dept of Natural Resources and Conservation, and the Natural Resources Conservation Service put into place the Candidate Conservation Agreement with Assurances, or often referred to as the CCAA. This put into place a strategic plan for recovering the Big Hole River Arctic grayling as well as providing legal protections for landowners who enroll and participate in the CCAA. The CCAA was a necessary step in recovering the Arctic grayling in the Big Hole because grayling live 90% on private lands, rendering private landowner cooperation absolutely essential.

The CCAA is managed by a team of committed agency members:

  • Emma Cayer, Arctic Grayling Recovery Biologist, Montana Fish, Wildlife and Parks
  • Jim Magee, Partners Program, US Fish and Wildlife Service
  • Mike Roberts, Hydrologist, Montana Department of Natural Resources and Conservation
  • Kyle Tackett, District Conservationist, Natural Resources Conservation Service

Each landowner enrolled in the CCAA program signs on to site specific plan for their property developed held by Montana Fish, Wildlife and Parks and the landowner that needs to be followed in order to receive legal protection. Plans are extensive and typically include a task list for riparian management plans, riparian and vegetation recovery, weed treatment, irrigation improvement, fish passage, and flow maintenance plans. Each landowner plan is monitored and results are reported annually.


The CCAA program is a 20 year agreement and was put in place as a result of the US Fish and Wildlife Service investigation of the Arctic Grayling as a Candidate for Endangered Species listing, to which the fish was added as a candidate in 1991.

Citing the extensive efforts and improvements for conservation specifically targeting the Arctic grayling as well as increasing populations, the US Fish and Wildlife Service in 2014 determined the Artic grayling was not a candidate for Endangered Species Act listing. The announcement was made August 19, 2014. Not everyone agrees with the US Fish and Wildlife Service decision. In 2015 a lawsuit was filed suing US Fish and Wildlife Service disagreeing with their decision to not list the fish on the Endangered Species Act, the outcome of which have not yet been resolved.

Working together the CCAA program has made impressive improvements. As of 2016, they have enrolled 32 landowners in 161,768 acres in the CCAA program that includes 214 miles of stream or river. They maintain, the most important factor in Arctic grayling recovery is the people – the folks who are employed to work on the recovery, the representatives of those who believe in the recovery, and most importantly the landowners.
