Lake Saint Clair Michigan, I am in the process of editing the ESP8266 and Sensors to record water temperatures at different depths.
This is data showing water volume for a reservoir. Reservoir devices are off the grid (no power, wifi) and use an AVR Iot Cellular Mini with JSN-SR04T sensors using cellular to post data. Variations use LiPo bat or capacitor plus solar panel for power.
Monitoring water levels to help automate water storage (tank 2 sensor being installed) and site temp/humidity..
