The Sreenty/Corduff site is comprised of two adjoining catchments- the northern catchment drains into Sreenty Lake (also known as Lough Namachree ) while the southern one is drained by a stream. The two catchments are 578 ha in combined area and 89% of the area is grassland with the balance in non-agricultural uses. The main farming enterprise is beef production with some dairying and sheep production.
These catchments are in an area where the topography ranges from alluvial flatlands to variously shaped, recurrent drumlins with fairly steep slopes and with intervening U-shaped valleys. These drumlin features were formed when the advancing glacial ice sheet moved over this area compressing the till deposits into interlocking hump backed hills. There are often small lakes in the valleys and this catchment has two, the larger of which is Sreenty Lake.
The soils vary with the nature of the till deposits from drumlin to drumlin. The underlying rock is mainly sandstone in this catchment and the glacial till is relatively free draining and can be quite shallow. Acid brown earths dominate the hill tops, with stagnic luvisols and gleys on the hill slopes, foot slopes and valley bottoms. Given the soil type and topography, phosphorus is considered the main nutrient at risk of loss to water.
Sreenty Lake is the water source for the local group water scheme. The lake outflow and the stream join just downstream of the two catchments and flows into the Annaghlee/Erne system.
