Description    


In 2024, DNR staff traveled to the remote Alexander Creek Drainage to conduct herbicide control of the aquatic invasive plant Elodea sp. The treatments focused on Alexander Lake (pelleted treatment) and the Sucker Lakes Complex (pelleted and liquid treatments) over 7 trips between June and September 2024.

Project Benefit    


Eradicating Elodea from the Alexander Creek Drainage will remove this invasive species from approximately 425 hectares of lake, restoring salmon habitat and preventing the infestation of Elodea to other lakes in the Mat-Su through float plane traffic.
