River Lee Country Park

Covering 1,000 acres (400 ha) on either side of the River Lee Navigation between Waltham Abbey and Broxbourne, it is an area of lakes, watercourses, open spaces and three Sites of Special Scientific Interest (SSSI) linked by footpaths and cycle tracks.

Since the 1930s the area which was originally part of the River Lea flood plain has been the centre of the sand and gravel industry, as a result there are many mature gravel pits.

In a joint effort by the St Albans Sand and Gravel Co Ltd and the Lee Valley Regional Park Authority the area has been transformed, with much of the park a Site of Special Scientific Interest (SSSI) [1] The park at the Showground site, Highbridge Street A121, Waltham Cross was the chosen venue for the 2012 Olympics canoeing events.

The site is now known as the Lee Valley White Water Centre.

Some of them form the Turnford and Cheshunt Pits SSSI.
