Pressures and risks on lakes

We assessed the pressures on lakes from alien species, diffuse source pressures, point source pressures, physical and morphological alteration, and water abstraction and flow regulation.

The results are displayed as maps and statistics, and can be found through the links below along with the risk assessment methods.

Alien species pressures on lakes

Alien species are non-native organisms that establish themselves in native ecosystems.
Diffuse source pressures on lakes

Diffuse pollution can arise from the way we use the land - both in rural and urban areas
Physical or morphological alteration pressures on lakes

Physical alterations to a river, lake, estuary or coastal water can cause habitat damage resulting in loss or decline of species.
Point source pressure on lakes

Discharges from sewage works and industrial processes can contain substances that can damage the ecology and quality of receiving waters.
Water abstraction and flow regulation pressure on lakes

Water is taken from rivers, canals, reservoirs, lakes or underground aquifers to provide public water supplies, for agriculture and industry.
