Hatchmere is a small mere and nature reserve in Delamere Forest, southeast of Frodsham, Cheshire, England.

It is an unusual mere because of the surrounding vegetation which consists largely of acidic heath and bog communities.

[citation needed] Notable animal species include the Hairy Dragonfly Brachytron pratense, Variable Damselfly Coenagrion pulchellum[1] and a rare caddisfly, Potomophylax rotundipennis.

[3] Rare plants for the area include Tufted Sedge Carex elata and Bog Myrtle Myrica gale.

A pressure group, the Friends of Hatchmere, was formed, and eventually the Wildlife Trust backed down and agreed to allow swimming in the lake.
