13 major invertebrate indicator groups were represented. In common with recent years, most samples had relatively low numbers, although fish were caught in several samples, including minnow, bullhead and stone loach. A nearby fisherman caught a roach and a small perch.
Stonefly nymphs, burrowing & swimming mayfly nymphs were present in most samples, the best result for over 10 years. Some samples contained good numbers of cased & uncased caddis fly larvae (including Hydropsyche & Rhyacophila species), more evidence of well-oxygenated water. Bloodworms, sludgeworms, leeches and other polluted water indicators were present in low numbers, reflecting a healthy river ecosystem here.
