Stop the Spread of this Aquatic Invasive Species
The more Elodea spreads the less control we will have over the outcome and cost to Alaskans. Call and report sightings of Elodea.
Elodea in Alaska
Thought first documented in 1982 in Eyak Lake, Cordova, land managers did not take notice of this plant until 2010, when it was found growing aggressively in Chena Slough near Fairbanks. Elodea is not native to Alaska, and it is the first invasive aquatic plant known here. It has the potential to impact freshwater resources and fish habitat statewide. A coordinated control effort is needed now!
In other places Elodea has invaded, it has dramatically impeded navigability, impacted native ecosystems, and made fishing problematic or impossible.
Elodea Around the World
Elodea has a long history as an invasive plant. It was introduced to Great Britain over a century ago, and has since spread to Scandinavia and across Russia to Lake Baikal.
Potential Impacts on Alaska
- Degrade Fish habitat and displace native flora and fauna.
- Make boat travel difficult and reduce recreation opportunities
- Endanger safe float plane operation.
- Alter freshwater habitats, including decreased flow & increased sedimentation.
- Reduce property values of adjacent landowners.
It Spreads Easily Because:
- Broken segments will form new plants.
- It can survive when frozen in ice and travel long distances downstream.
- Leaf edges are very finely toothed.
- Leaves in whorls of 3 or occasionally 4.
- Leaves are 1/4-1/2" long & 1/8" wide.
- Stem is a lighter green than the leaves and grow in a tangled mass.
Are Other Waters at Risk?
YES! If nothing is done, Elodea will spread downstream and into new waterbodies - potentially carried by floatplanes, anglers, and recreational users. Elodea prefers cool, clear, slow waters with silty bottoms.
Known Locations of Elodea in Alaska
- Fairbanks: Chena River, Chena Slough, Chena Lake
- Cordova: Eyak Lake, Alaganik Slough, Mckinley Lake, Martin Lakes
- Anchorage: Little Campbell, Sand Lake, Delong Lake
How You Can Help
- Leadership, initiative, cooperation, funding, and fast action are all needed to solve this growing problem.
- Support management efforts statewide.
- Volunteer to help educate stakeholders.
- When you are on the water, follow simple procedures to prevent spread of this plant.
Follow these simple guidelines:
- Remove all visible mud, plants, fish/animals from equipment.
- Eliminate water from all equipment before transporting. Much of the recreational equipment we use can collect water and harbor hitchhikers.
- Clean and dry anything that came in contact with water. Use hot (140?F) or salt water if possible, allow 5 days to dry before entering new waters.
Never release plants, water, fish, or animals into a body of water unless they came from that water body.
Aquarium plants and animals may be able to survive in our Alaskan waters! Dispose of aquariums responsibly, not by dumping them into waterways.

AVAILABILITY OF DRAFT ENVIRONMENTAL ASSESSMENT (EA) FOR STORMY AND DANIELS LAKE ELODEA ERADICATION PROJECT
The Department of Natural Resources Division of Agriculture has prepared a Draft EA that considers the proposed fluridone and diquat treatment of Stormy and Daniels Lake for the purpose of eradicating the invasive aquatic elodea population and maintaining ecological integrity of the waterways on the Kenai Peninsula. Copies of the draft EA are available online at http://dnr.alaska.gov/ag/ag_dn.htm. Copies can also be obtained by contacting Brianne Blackburn, 5310 S. Bodenburg Spur Rd, Palmer, AK 99645, by phone at (907) 745-8785, or by e-mail at Brianne.Blackburn@Alaska.gov. Comments on the Draft EA must be submitted to Ms. Blackburn at the above mailing or e-mail address no later than 4:00pm on July 12, 2013.
