Trinity Broads

The Trinity Broads are five interconnected lakes, isolated from the rest of the Broads system. The most northerly Broad is Ormesby, then Rollesby, Lily, Ormesby Little and finally Filby Broad in the south. These Broads cover 162 ha of open water in total, with 21km of broadshore habitat including fen meadow, tall herb fen, littoral reed bed and alluvial forest.

The site is owned by Essex and Suffolk Water and managed in partnership with NWT. The broads are a significant fresh water supply with approximately 5 million litres of water abstracted each day, supplying 80 thousand homes in the surrounding villages and Great Yarmouth.

Further details of the conservation management of the site and its species can be made available by contacting the Warden directly:  07711 439180 or
