Description: This feature class contains the major natural and artificial lakes of Africa from the Natural Earth "Lakes + Reservoirs" geodatabase, version 4.1.0, at 1:10,000,000 (1:10m) resolution. The dataset is primarily derived from World Data Bank 2 with numerous reservoir additions from other sources, primarily imagery. The diminishing areal extent of the Aral Sea and Lake Chad derives from recent satellite imagery. In this feature class, the attribute field names have been modified from their original source to fit our GIS attributes table schema; descriptive field aliases were created from the original field names in the source data.

Copyright Text: This feature class was compiled by Abraham J. Padilla (USGS) from its original source: Natural Earth Lakes + Reservoirs (https://www.naturalearthdata.com/downloads/10m-physical-vectors/10m-lakes/). All versions of Natural Earth raster + vector map data are in the public domain (https://www.naturalearthdata.com/about/terms-of-use/) and can be accessed at https://www.naturalearthdata.com/downloads/.
