Chloride Impairment
Jon Hartman represented the LJIS at the Ramsey Conservation District Aquatic Invasive Species Forum on March 30. At that meeting we learned some disturbing news. John Manske of Ramsey County Lake Management has been taking Chloride and Secchi disk measurements at Lake Johanna (and other area lakes) for many years, and has been researching Chloride levels. He has determined that Lake Johanna is in danger of Chloride impairment in 15 years. Little Johanna is already impaired. Chloride comes into the lake primarily from salt spread on roads, sidewalks, and parking lots. What does this mean to Lake Johanna?  Please read the resources about this issue on the LJIS website under the Resource Center > Water Quality section of the the LJIS Web site, including slides from John Manske’s presentation, a chart showing Chloride concentrations from 1987-present, and a recent StarTribune article about Chloride impairment.

Jon Hartman has been in contact with Jon Manske. The LJIS board will be exploring ways that we can help reverse this trend, so contact a LJIS board member if you have ideas.

AIS Detectors
Bob Teeling and Gregg Larson have both enrolled in the Aquatic Invasive Species (AIS) Detector training being offered by the Minnesota Aquatic Invasive Species Research Center (MAISRC). It will be valuable to have these lake residents trained in AIS identification. If you observe any aquatic plants or creatures that you suspect might be Aquatic Invasive Species, contact Bob, Gregg, or a Board member.

AIS Ambassador training
The Ramsey Conservation District is considering offering “AIS Ambassador” training: "As an AIS Ambassador you will undergo training by the MN DNR. This will prepare you to educate the public about invasive species at public accesses. While the AIS Ambassador role is strictly educational, it plays an important part in reminding boaters of the importance of protecting our waters.” If you are interested in this opportunity, contact Keith Gilbert and he will put you in touch with the Ramsey Conservation District AIS Coordinator.
