In most cases when rotenone is used, the lakes will be treated in the fall. Post treatment studies will determine when the treated lakes have detoxified. Once detoxified, they will then be restocked with pure westslope cutthroat trout the following spring.
During the summer of 2007, additional cutthroat trout genetic samples were collected to help guide management in future years. If some of the lakes on the "Tentative Treatment Schedule for WCT Project" have responded to past stocking of pure westslope cutthroat, it is possible that rotenone treatment may not be needed. Treatment options will be determined on a lake-by-lake basis.
Current plans call for treatment of about two lakes containing hybrid trout each year over the next nine years.
