Monitor phophorus and chlorophyll A. Lake Arbutus was last monitored in 2005 at which time the average phosphorus concentration was 124ug/L and the average Chlorophyll a concentration was 49ug/L. Recent complaints by lake users indicate algal blooms are common and interfering with designated uses of this lake. There are currently no CLMN volunteers associated with Lake Arbutus able to conduct chemistry monitoring.

Chemistry samples for total phosphorus and Chlorophyll a will be collected in Lake Arbutus to determine if current in-lake conditions meet water quality standards and to verify, per WisCALM guidance, whether 303(d) listing is appropriate for this lake. This project will fund the first of two years of sampling.
