The Shournagh demonstration catchment rises in the Boggera Mountains to the North West of Cork City. It flows in a South Easterly direction, through the village of Tower, before joining the river Lee near Carrigrohane, West of Cork City.


The demonstration catchment has an area of approximately 130km2.  Three of the five sub basins which make up the sub catchment have a high status objective, with the other two inputting into these and so potentially impacting on their status.

None of the three high status objective water bodies in this sub catchment are currently meeting their objective: one has fallen to good status and two to moderate status in the last monitoring cycle.  All three are considered to be at risk of not meeting their objectives under the River Basin Management Plan.

The significant pressures which have been identified on these water bodies are: agriculture, hydromorphology, urban waste water, domestic waste water and urban runoff.

Soils in this catchment are free draining, which is somewhat unusual in the context of high status objective rivers.  The pollution impact potential (PIP) maps produced by the EPA show very high PIP for nitrate and very low PIP for phosphorus.
