This dataset documents the surface water area time series for all studied lakes in China during the period of 2000-2019 (in a single csv file format). Note that:
1. We used the lake polygons from the GLAKES dataset to define the boundary of lakes in China. The GLAKES polygons can be obtained via the following link: https://zenodo.org/record/7016548.
2. The lake area values can be regarded as a reflection of the annual average of the surface water distribution within lakes (see Section 2.3 of this paper for details).

The dataset includes the following attributes:
1. GLAKES_ID: the identification of each GLAKE lake polygon. 
2. Year: the specific year for the time-related variables presented below.
3. Reservoir_flag: a indicator to identify whether the lake is a manmade reservoir (value=1) or a natural lake (value=0).
4. Area_raw: the surface water area for each lake before recovery (square kilometers).
5. Area_dr: the surface water area for each lake after recovery (square kilometers).
