hi mate,
There are a few around, Monks lakes, Elphicks lakes and orchard place farm down in paddock wood to name only a few. It depends on how far you are willing to travel as well. but those three would suit your needs.
You could phone up the local ea office and they do a book on where to fish in the county so that would be a good starting point or go into one of the tackle shops around maybe maidstone tackle.
if you want any futher info google is your friend or i will try to help.
