Latchmore Brook

The Latchmore Brook is a significant stream in the New Forest, Hampshire, England. It rises from the elevated gravel plateaus in the north of the Forest, north of Fritham, and drains into the River Avon north of Ibsley.

The stream's catchment is open heathland, deciduous woodland, silvicultural inclosures and, in its lower reaches, small scale pastoral farmland; as such there are no consistent sources of pollution and the stream's course and character has largely remained free from artificial modification. Historically, the greatest human impact on the brook was connected to the Schultze Gunpowder Factory which was established in the 1860s at Eyeworth Lodge near Fritham. The factory required large volumes of water and this demand was met by damming the brook to create a reservoir . The problem of sulphuric and nitric acid discharges contaminating the river, killing fish, only ended when the factory closed in the 1920s.
