GRAND LAKE ST MARYS WATER QUALITY UPDATE –
SEPTEMBER 2020
STEPHEN J. JACQUEMIN
WRIGHT STATE UNIVERSITY – LAKE CAMPUS,
AGRICULTURAL AND WATER QUALITY EDUCATIONAL CENTER
Stream Wetland Update
Nutrients and Sediment
VERY low nitrogen values in the stream this summer
– outstanding reductions in Phosphorus this year
Stream and Wetland Flows
• Lower spring and summer stream flows this year
compared with several previous years
• CWC flowing ~1 to 4mgpd this spring/summer
• PC recently added new pump – flows have
DOUBLED – now moving ~1.25mgpd
• Higher than average load reductions for 2020
Infrastructure Improvements
• Settling pools in PC were dug out – will be
expanded in the future
Annual Update for 2020
• Expected to be released February 2021
Littoral Wetland Update
Prairie Creek
• Sedges are taking root – recent survey found
hundreds growing and expanding along the
western edge of the littoral area
• Thank you to LIA for funding this purchase
GLSM Microcystin Update
Long Term Trends
• 2 primary spikes in toxins – late
spring/summer AND late fall
2020 Data Comparison
• Low winter values compared to
past years
• Spring values consistent with past
years
• Summer values higher than last
year but lower than 5 year average
• Toxins remain high – water unsafe
for direct contact
New Watershed Projects
Saturated Buffer in Beaver Ck Watershed
• Will involve rerouting tile drainage from an
active field with high soil test P levels into a
riparian area to filter dissolved nutrients
• Project represents a potential tool that could be
used on a wider scale around the watershed
