The following is a press release from Montana Fish, Wildlife and Parks.

This is the second rotenone treatment as part of a multi-phased project to remove non-native fish and restore native westslope cutthroat trout to the North Fork of Spanish Creek. Rotenone is a naturally derived substance commonly used in fish restoration efforts that is toxic to gill-breathing animals and breaks down quickly in the aquatic environment.

Westslope cutthroat trout are native to Montana but have experienced substantial declines in distribution and abundance throughout their historical range due to habitat degradation and hybridization with rainbow trout. However, the results of this restoration project will more than double the number of stream miles occupied by westslope cutthroat trout in the Gallatin River drainage.
