Howden Dyke Island

Howden Dyke Island is a 19-acre island in the River Ouse, Yorkshire. More accurately a shoal between seasonally varying flows, the area regularly above water is roughly 1,380 by 890 feet . A larger example of this same feature is visible where the Ouse widens into the Humber Estuary, 12 miles downstream at Faxfleet.

The island has also been known as Hook Island and Silverpit Island, and was formerly used for agriculture, and connected to the riverbank. However, this land use combined with the digging of a fishing pond in the 1920s, eroded a channel to make an island in the 1950s, subsequently washing away soil until the island was inaccessible and, at high water, less than half its current size. Today, vegetation on the island and the riverbank opposite help to protect against erosion. The land has been used for wild-fowling, and is home to a wide range of birds and other wildlife. It forms unit 02 of the Humber Estuary Site of Special Scientific Interest, and is in favourable condition.
