Hello
Just back from two weeks holiday abroad and was too busy just before we went so I am about a month out of date with the conditions at Kildrummy. So far this year I have caught one kelt. April was slow, thin hatches and no fish showing or even looking at a spider. I would guess it will have improved in May but I have not had a look at the river and I have no idea how the hatches are going just now. If the caddis have started coming off I would guess an evening would be more productive than the day time but that's just a guess. It will be next weekend before I get a chance myself.
Sorry I can't be more help.
