The table below (PDF) are Dissolved Oxygen levels measured this winter season (depth column is from the surface down to lake bottom). Despite the frigid February, Dissolved Oxygen’s remained well above a rainbow’s Dissolved Oxygen threshold of 3 mg/L. Aerators are still running and will likely be offline in the next couple of weeks before ice out – ice thickness ranged 50 – 80 cm last week.
