Hornsea Mere

Hornsea Mere lies west of the town of Hornsea in the East Riding of Yorkshire. It is the largest freshwater lake in Yorkshire, covering 467 acres. The mere is only 12 feet deep at its deepest point and sits 26 feet above sea level. Several small streams feed the mere, and a sluice gate controls the short outflow to the North Sea. The lake has been used for military purposes, serving as a base for the Royal Naval Air Service during the First World War. The mere is important for wildlife and attracts many bird-watchers. It is a Site of Special Scientific Interest and a Special Protection Area for birds. Hornsea Mere supports a variety of species year-round and is internationally significant for its migratory gadwall population. The lake’s shallowness encourages a wide range of swamp and fen plants to grow. It was also featured in the BBC television programme *Seven Natural Wonders*. Visitors can enjoy rowing, sailing, boat trips and fishing on the mere. Hornsea Sailing Club operates from the lake, and the area around the water includes a boatyard and a café. On the eastern shore stands Kirkholme Nab, a small peninsula where the Royal Naval Air Service once had a seaplane base. Some brick buildings from the First World War remain in use today. The mere’s military past adds another layer of interest to its natural beauty.
