The North Star Community Charter School (see full article) kids went out on April 12th (Brian and I took them on his boat) on our first water quality sampling of the season. We sampled all four sites for temperature, dissolved oxygen, pH, and water clarity (Secchi readings) The DNR wants readings as soon as possible after ice-out.
Sites were: the Main Basin (off Wilcox Island) the Narrows, the Dam, and the Deep Hole below the Look-Out. We also took samples for phosphorus levels at the Dam and the Narrows. The kids operated the equipment (secchi disc, Hoch O-2 meter) and did all of the recording.
