The University of Maryland, NASA and the USDA have worked together to create a website compiling lake heights from around the world determined by satellite radar altimetry. The Global Reservoir and Lake Monitor can be found at: http://www.pecad.fas.usda.gov/cropexplorer/global_reservoir/.
Percent Biogenic Silica and 14C dates for piston cores 1P, 2P, 3P, 6P, and 7P, collected from Lake Victoria in 1995, are available from NOAA's National Geophysical Data Center.
