%X The change in lake water storage capacity is a unique indicator of natural climate change in the Qinghai Tibet Plateau (TP). However, the region still lacks comprehensive lake water storage data, especially for lakes smaller than 10 square kilometers. In this dataset, we utilized Landsat imagery and digital terrain models to conduct an annual relative lake volume (RLV) survey of 976 lakes with an area greater than 1 square kilometer in the Qinghai Tibet Plateau Internal Flow Basin (EBTP) from 1989 to 2019. Our method first identifies individual lakes, determines their analysis range, and calculates the annual lake area based on land remote sensing satellite images. Then derive the relationship between lake area and altitude, estimate the lake surface altitude, and calculate RLV. After verification and comparison with several existing datasets, it was found that our data is more reliable and comprehensive. Our research provides complete long-term lake water volume change data for the region, which is a supplement to the existing lake dataset.
