Portneuf River Basin

Portneuf watershed map


The Portneuf River is located in southeast Idaho, and follows a path of about 156 km from the east side of Yandell Mountain, flowing south on the east side of the Portneuf Range, and north between the Portneuf and Bannock Ranges, and on to the eastern Snake River plain where it enters the Snake River.

CERE faculty and students conduct research throughout the Portneuf watershed and partner with government agencies to maintain an intensive monitoring program. This community-based monitoring program provides data to detect changes within the watershed and is an excellent basis to address ecological research questions.
