***General Introduction***
Water clarity, represented by Secchi disk depth (Zsd), is the first-order indicator of water quality. This dataset contains Zsd of 86 major large lakes with an area greater than 30 km2 in East China estimated using a random forest regression (RFR)-based Zsd model. Scientists from optical remote sensing and aquatic sciences can use this dataset for their research.

***Coverage spatial***
East China (18.1¡ã-53.5¡ãN, 104.5¡ã-134.9¡ãE)

***Description of the data in this data set***
For excel data:
Zsd: Secchi disk depth (m)
Area: Lake area (km2)
For tif data:
Zsd: Secchi disk depth (m)
Spatial resolution= 300 m
