LakeLevel is a rugged ultrasound sensor that measures water level from above the surface — no probe in the water, nothing to foul. It reads every 15 minutes, 96 times a day, to an accuracy of ±0.02 ft, and runs roughly ten years on its own battery at standard reporting frequency.

It mounts on a dock post, bridge, or boathouse in about fifteen minutes with no specialised training, connects over cellular or Wi-Fi, and is IP68-rated and CE and FCC compliant.
