Right Steve.
The Mist has a general depth of 8 ft. Good car parking, but you need a key for the gate, availiable from WAA or Baileys tackle next to the Mist, on production of your WAA card. I think it's about 6-8 acres in size.
The weed has died down, If it is Pike you are after, they go to somewhere around 18 lb. A 14 came out at the weekend. Also some good eels are present. One of 7.11 came out last year. The opposite end to the car park produces the best. You won't have a problem during midweek, but it can get busy at weekends with anglers spinning for Pike.
You could also fish the Mersey for Pike and eels at the back of the Mist, just over the hill on the left hand side. We now have that stretch on the card.
