ferry meadows is a good start,get a push bike and see whats about,always some about, some pegs can be fished all year but most follow the season.
stanground lock a good place,
or the boathouse near the old hospital,
the old a47 at castor along the bank thats looks across to the sailing lake,
back water on the thrope golf course,
dont need to pre bait these spots but it can help.
then any stretch all the way up,tho the oundle area is still the best due to the 98 floods
