The stream is no trout place. The lower altitude and relative closeness to the urban area make the chub the predominant species. Honest chub that grow up to 40-50 cm. are not seldom. Still and all, chub is the only fish that one catches here, at any given day. Yet the place holds a secret. When water turns to washed out caffeine, trout may appear from out of the blue and tweak out.
