I agree with the above regarding good numbers of fish getting caught from may until August then an another alarming slump.
I also agree with your comments about been unsure of how many fish are actualy in the river, bearing in mind spring and summer fish are very willing takers to start with
as long as ive fished the eden it always did have a decent run of summer fish , but most of us were out fishing for sea trout to take advantage of that.
