The Arrowsmith River in the Mid West region of Western Australia.
The first European to discover the river was the explorer George Grey in 1839 who named it after the distinguished English geographer John Arrowsmith.
The river commences just South of Arrino and North West of Three Springs near the Midlands Road and flows in a westerly direction for a length of 85 kilometres (53 mi) to the coast and terminates in a swampy area about 5 kilometres (3 mi) from Cliff Head.
The river drops a total of 219 metres (719 ft) in elevation over the course of its length.
The salinity levels in the river are often higher than 1000 mg/L due to recharge of brackish run-off water but the potential bore yields of the catchment are quite high.[5]
