There is one main river basin that runs through Waltham Chase; the “Shedfield Stream” as it is known by the Environment Agency. This is part of the South East river basin catchment area.

The river is currently classified as having a status of ‘poor’ for its Current Ecological Quality. High in ammonia and phosphates.
