Leven Operational Catchment

About

The operational catchment lies largely within the Lake District National Park, including Englands largest lake Windermere, and drains via the River Leven into Morecambe Bay. Key species include Sea trout, Atlantic salmon and Artic charr, all under pressure due to a combination of enrichment and increasingly fluctuating river flows / lake levels. Land use is dominated by sheep and beef farming, with a vibrant tourist industry focused around the tourist centres of Bowness-on-Windermere, Ambleside, Hawkshead and Grasmere. There is a significant public water supply abstraction on Windermere and an increasing number of hydro-electric schemes across the catchment.

Reasons for not achieving good status by business sector

The issues preventing waters reaching good status and the sectors identified as contributing to them. The numbers in the table are individual counts of the reasons for not achieving good status with a confidence status of 'confirmed' and 'probable', where the latest classification is less than good status. There may be more than one reason in a single water body. Note, table does not include reasons for deterioration.

Objectives data for Leven Operational Catchment

Ecological status or potential objectives for surface water bodies

Table summarises the ecological status and ecological potential objectives set for water bodies in the river basin management plan. Each water body is only counted once in this table. Each water body objective consists of a target status and a date when it was, or is expected to be, met.
