Tone Operational Catchment

About

The River Tone is 33 kilometres long from its source to the confluence with the River Parrett, covering an area of approximately 414 square kilometres. The River Tone and its tributaries drain Exmoor, the Brendon, Quantock and Blackdown Hills. Downstream the Tone enters Clatworthy Reservoir and runs South to Taunton; the Tone becomes tidal at Newbridge before joining the Parrett at Burrowbridge. The Bridgwater and Taunton Canal (24.6km) leaves the Tone in Taunton and flows on to Bridgwater to the tidal River Parrett. Predominant land uses in the catchment are permanent pasture, arable and sheep and cattle grazing and woodland.

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 Tone 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.
