Pack River Station

Water Quality Monitoring Station

Lake Pend Oreille

Status – No Known Issues

Citizen Scientist(s): Kevin Kittleson

The Pack River is the second largest tributary to Lake Pend Oreille and is located in Bonner and Boundary Counties. It flows over 40 miles from the Selkirk Mountains into the northeastern corner of Lake Pend Oreille. It is significant habitat for bull trout, westslope cutthroat trout, and many other wildlife species. You can even find freshwater mussels in the river! Near the mouth of the river is the Pack River Flats Wildlife Management Area managed by the Idaho Department of Fish and Game and The Idaho Club’s expansive golf course. The Pack River Watershed Council was formed in 2001 to coordinate watershed restoration projects along the river.

This site was added in 2021 in order to get a more representative sample of what is flowing into our lake from the Pack River’s watershed. This site replaced our Pack River Delta site, which was monitored from 2012 – 2020.
