Blue Green Algae / Cylindro


BGA sampling procedures and services provided by the WI State Lab of Hygiene to collect a sample or advise others how to do it in response to a severe bloom, human or animal exposure or illness. DNR staff role is to help facilitate sample collection and analysis at the local level, but we do not have the staff or resources to respond to most situations ourselves. There is currently no standing budget for these analyses, so costs would need to be covered locally.

Data obtained for the Wisconsin HAB Surveillance Program is primarily intended for documentation of conditions co-occurring with human and animal illnesses potentially related to harmful algal bloom exposure. Cyanobacterial cell densities and chlorophyll concentrations sampled for the program may be able to inform public health decisions by local health authorities, especially in the case of lakes with historic or ongoing problems.
Response regarding algae bloom
Response to an algae bloom 8/4/2014
Jim Kreitlow received a sample of "lake balls" from a homeowner on Pine Lake and identified them as containing a highly-branched Cladophora, which is a kind of filamentous green algae. Jim sent Gina LaLiberte part of the sample to look at and she confirmed that it is a Cladophora species that is now known as Aegagropila linnaei.
