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]).
