As you know Stephen, the match is off but we may fish there in the future as its an easy venue with some good Flounders.
Search for Dock Road, Connahs Quay on Google maps and it will show you the area. I cant get the link to work otherwise i would put one up.
Come off the main road before you go over the new bridge and go towards Connahs Quay on Kelsterton Road. As you go up the hill Dock Road is on the left and you fish behind some factories straight out of the car but fresh water kills the fishing.
Never been there myself but thats the info i was given about the place. Dont know if anyone else can add anything?
