Foss Operational Catchment
About
The River Foss is a large tributary of the river Ouse, which starts as a spring near Oulston reservoir, and flows south, in a series of wide meanders, through the Vale of York to join the river Ouse in York, just downstream from Cliffords Tower. The catchment is largely rural and the mainly low lying land surrounding the river Foss is intensely farmed, until it becomes more urbanised as it flows through the City of York.

Challenges data for Foss Operational 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.
