In 2015, TLA began investigating Golden Brown Benthic Algae (GBA). This project is ongoing. We will update this page with additional information as it becomes available.
As work continues on investigating GBA, work has been done on the tools used to collect information. This report contains information on methodology being used: Dialysis Tubing 2018 Equilibration Study
Here is the report created by Dr.R. Jan Stevenson in 2016: 2016 Study of Golden Brown Algae on the Bottom of Torch Lake, Lake Bellaire, and Clam Lake
On April 27, 2017, Dr. Becky Norris, Three Lake Association, TLA, Water Quality Chair presented the Torch Lake GBA story with findings from research studies performed in 2015 and 2016 with the assistance and guidance of Drs. Pat Kociocek, Rex Lowe and Jan Stevenson. Here are the GBA Mini Symposium Summary Notes. Here is the Mini-Symposium on GBA Group Photo & Names if the participants.
On October 28, 2016, Becky Norris presented information on the Golden Brown Algae (GBA) study to the Freshwater Summit. Here are the slides and her notes exlaining the slides:
On July 14, 2016, university experts assisting us with the study of GBA presented the findings to date and helped us understand this recent phenomenon throughout our waters. The speakers included:
- Dr. Rex Lowe, U of M Biological Station
- Dr. Pat Kociolek U of M Biological Station
- Dr. Jan Stevenson MSU
Here is a PDF of the presentation that was made: Torch lake Presentations 7-14-16
In the spring of 2015, Three Lakes Association (TLA) retained the services of two professors (internationally recognized diatom experts), Rex Lowe and R. Jan Stevenson, to work with TLA’s volunteers to design and conduct an investigation of golden brown benthic algae (GBA) in Torch Lake. Their complete scientific reports, are available here.

In late February, Three Lakes Association was asked to present to the Leelanau Clean Waters Group to update them on our Golden Brown Benthic Algae (GBA) research. A slide presentation was assembled by our Water Quality Committee. We have put the slides together with notes to bring you Watershed 101: GBA: GBA Review Feb 2016
