How the data was collected

High-frequency data were collected using sensors attached to a rope deployed from a buoy at the lake’s deepest point. Dissolved oxygen and temperature were recorded every 10 minutes at depths ranging from 1.52 to 7.52 meters. A water level sensor, placed at 4.52 meters, recorded data every 12 hours. Manual sampling occurred every 2–4 weeks and included measurements of nutrients, dissolved organic carbon, chlorophyll-a, Secchi depth, and additional temperature and dissolved oxygen readings using a YSI probe.
