Welcome to the website of the Lea Catchment Partnerships – bringing together people and projects for the benefit of the River Lea and its tributaries.
The River Lea and its tributaries - the Mimram, Beane, Ash, Rib, Quin and Stort - drain over 1000 km2 of south-east England. These rivers include rare and precious chalk streams, canals and navigations, and urban watercourses.
The Storymap for the partnership can be read here.
