I grew up just a bit further up Silkmore Lane, back in the mid 00's it used to flood like that quite frequently. I remember walking home from school (Rising Brook) one day (probably 2006ish) and finding the entire road flooded about 2 (or 3) feet deep, I tried to wade through it to get home but the friends I was with at the time made a more sensible decision and walked back through town. Cars chanced it and got stuck, children swam in it...
I only have one picture left from back then, at the top of the picture is the co-op and to the right is the housing estate (that was brand new at the time, I think?). I never really understood why they built that housing estate there, the old caravan park used to flood constantly... hopefully the height they built it at has prevented the flooding.
The repugnant smell of that brook is still burned into my nostrils from childhood, I can't imagine it's pleasant to be around there right now.
