The article reports low water storage at Baihe Reservoir in mid-2018, with storage said to approach zero, largely because of accumulated silt. Typhoons disturb the water and resuspend sediment. Impurities and silt can harm crop growth, while electrochemical measurements such as pH and EC are also important.
A proposed answer to sediment surveying across a large reservoir
The source describes Baihe Reservoir as about 170 hectares, requiring 100–150 measurement points. Traditional kayak-based water-quality surveys reportedly needed at least a week to visit all points, while wind and waves could change sediment conditions during the survey. Sediment measurements also inform dredging intervals and storage estimates for agricultural water in the Chianan Plain. Persistent wind or rain can prevent adequate measurement.

The article says original supplier assisted the Baihe Reservoir management authority with a water-quality drone to speed measurement and reduce labour. Aerial observation identifies sediment distribution and helps target heavily affected areas.
The source describes a drone that can fly and float, measuring water quality 50 cm below the surface. It reports real-time IoT data return, a 30-second single-point pH measurement, automatic collection of sediment-condition information and 50 measurement points per day, improving survey efficiency.
Published figures and conditions are retained from the source. Confirm the exact configuration, test setup, date and applicable scope before using them as an acceptance requirement.
