Caldecote is still a fairly 'new' water, and doesn't get much attention. if lure fishing is your thing, you could do worse that taking a leisurely stroll along the canal, perhaps starting at Peartee bridge marina, and wandering up towards Springfield.
My last lure session on Furzton didn't produce a sniff, and I have had plenty of lure blanks on Willen, then one day had four fish in six casts (biggest a mid double) and three of those fish I landed were followed in by much bigger fish - which I never caught, of course
But then, that's pike fishing!
