Determining stream of origin and spawning site fidelity of salmonids in the Upper North Platte River drainage using otolith microchemistry

Understanding tributary use of fish in the North Platte River is crucial for successful management of a blue ribbon wild trout fishery.


July 2014 - December 2017


The Upper North Platte River watershed supports a nationally recognized and important wild trout fishery. In Wyoming, there are 76 miles of the North Platte River and 11 miles of the Encampment River which are classified as Blue Ribbon streams (WGFD 2011). While trout are not native to the drainage, they were stocked starting in the 1880s and have been managed by WGFD as a wild fishery since the early 1980s. Trout species present include rainbow, brown, brook, and cutthroat trout. The productivity of this fishery is dependent on accessibility to spawning habitat in tributary streams. However, we still do not know which tributaries are most important for trout spawning.
