Hi,

I have to appologise for delay with r.lake. Not everything is going always as 
planed.

I attached r.lake source code (no changes) and simple description file. I'm 
not english native speaking person and almost offline (expedition) and have 
no dictionary - feel free to correct my text.

If I can help in any way - feel free to contact me. 


wbr,
Maris.
