The District monitors water quality and levels at multiple points throughout the District. These points are strategically placed to help pinpoint areas for protection and restoration. Parameters tested include Total Phosphorous, Orthophosphorous, sediment, and E-coli.
Staff also record discharge throughout the summer to help determine total pounds of nutrients passed through each sampling point.
Water quality in District Streams is directly related to the precipitation we receive in any given year. In 2019, we experienced heavy rainfall causing streams to swell. With increased flows come increased loads. In places as much as 150% more lbs. of phosphorous was observed in 2019. The lakes in the district tend to act as “buffers” catching nutrients from streams and diluting them throughout the lakes. This can be seen at multiple points throughout the District.
Water levels started high as streams opened up in the spring. High water one foot over the gauge was reported on Campbell Creek at 230th St. Water levels receded after that until early July when the District received multiple large rain events. Large fluctuations in water levels and phosphorous loads were reported as large rain events passed through.
A marked increase in concentrations from the Rice Lake Complex was also observed from these rain events. On average, phosphorous loading increased 1.5X through the Complex. The same phenomenon occurred through the Ditch 14 Wetlands between Lake St. Clair and the Pelican River.
