Rostherne Mere
Rostherne Mere is a natural lake in Cheshire, England. It is the largest of the Cheshire meres with an area of 48 hectares and a maximum depth of 30 metres.〔Natural England. ''(Rostherne Mere NNR )''. Retrieved 26 April 2012.〕〔Guest, Jonathan & Malcolm Hutcheson (1997) ''Where to watch birds in Cumbria, Lancashire & Cheshire'', Christopher Helm, London.〕 It lies to the north of Rostherne village and to the south of the M56 motorway. Because of its importance for wildlife, the lake, together with neighbouring areas of woodland and pasture, has been declared a national nature reserve, a Ramsar site and a Site of Special Scientific Interest covering 152.9 hectares.〔Natural England. ''(Rostherne Mere: Citation )''. Retrieved 26 April 2012.〕
==Geography==
The lake lies on thick sedimentary deposits of glacial origin above marl and salt-beds.〔Ratcliffe, Derek A. (1977) ''(A Nature Conservation Review, volume 2: site accounts )'', Cambridge University Press, New York.〕 It was probably formed by a combination of retreating glaciers creating a kettle hole and subsidence caused by the underlying rock salt dissolving away.〔 The lake is fertile and base-rich with high levels of phosphate, nitrate and ammonia.〔 Nutrient levels have risen as a result of inflow from surrounding farmland and streams and because of the droppings from large numbers of roosting birds.〔
