The River Trym is a short river, some 4.5 miles (7.2 km) in length, which rises in Filton, South Gloucestershire, England. The upper reaches are culverted, some underground, through mostly urban landscapes, but once it emerges into the open it flows through a nature reserve and city parks before joining the tidal River Avon at Sea Mills. A medieval water mill near its mouth gave the area its name. Abona was a Roman port at the mouth of the Trym which provided an embarkation point for journeys across the River Severn to south Wales. In the 18th century there were short lived attempts at creating a port and a whale fishery here. The name Trym appears to have Anglo-Saxon roots. In recent years silting problems, caused by urban development, have caused some difficulties, but alleviation works have helped reduce the problem.
