About this water

The Allan runs off the Ochils and joins the Forth near Bridge of Allan, and for its modest size it is one of the most productive little trout rivers in the Central Belt. It carries a proper Lowland insect population — big dark olives in March, medium olives through May, caddis in the evenings — and holds wild brown trout throughout. The banks are easy, the wading is straightforward, and the fishing is democratically priced through local clubs with day tickets. A couple of small sea trout run up from the Forth in summer but nobody fishes the Allan for them. You fish it for wild brown trout on spiders and dry fly, which is exactly what it asks of you.
