ILEC World Lake Database

1. About

In 1994 scientific and socio-economic data on the environments of 217 lakes and reservoirs in 73 countries have been compiled into five volumes of the Survey of the State of World Lakes (WLDBook) out of a joint ILEC/UNEP (United Nations Environment Programme) project.  (Foreword to the WLDBook)  The data and information were collected according to standard questionnaire sheets and are categorized into 14 areas as follows. Later the data became available on our web site in the form of html documents. Subsequently in the current web application, most of the data (A~J) are packed into individual files and made searcheable. Visitors can consult each data in respective pages shown at the top. Currently the database has additional three hundreds and seventy lakes with fundamental data (A~D) in addition to the original lakes.

ANNOUNCEMENT : As of August 2017, the lake code system used in this database has been changed. Previously some lakes had the "S-" prefix such as SAFR-***, SASI-***, SEUR-***, SNAM-***, and SSAM-***. Now the "S-" prefix was removed and the corresponding trailing number is set greater than 200. Please refer to the following file for the full detail. (lake_code_2017.txt)  No alteration to the lake code for the original 217 lakes has been made and you can distinguish those by their two digit trailing number. If any reference to this database is set by using lake codes, please update that accordingly.

2. How to Use

You may want to search data for a specific lake or a specific data type. For the former case, you can directly search a lake name ([lake by name]) or, if you don’t know a lake name but know a country name, through a country list ([lake by country]). For the latter case, you can search using [data list]. Additionally the entire data can be searched by entering the key word ([Key Word Seach]).
