Apologize if this is not the appropriate forum for the question. 

I am trying to access the content of Category pages from either the dump or APIs. 

For example, I would like to get a complete list of rivers

http://en.wikipedia.org/wiki/Category:Lists_of_rivers

The API does provide the content but it is throttled 

https://en.wikipedia.org/w/api.php?action=query&list=categorymembers&cmlimit=max&cmtitle=Category:Lists_of_rivers&cmsort=timestamp&cmdir=desc

Therefore I would like to find the content in the dumps.  However, I cannot find this information in the dumps. I have looked inside

http://dumps.wikimedia.org/enwiki/latest/enwiki-latest-pages-articles.xml

and find nothing there. The pages are referenced in the the page SQL dumps

http://dumps.wikimedia.org/enwiki/latest/enwiki-latest-page.sql.gz

Do any of the dumps contain the category page content?

thank you
