 To ensure the long-term sustainability of lakes and ponds, key issues that should be considered in their design include catchment hydrology and water level, and layout of the pond/lake (oriented to dominant winds to facilitate mixing.Hydraulic structures (inlet and outlet zones) should be designed to ensure adequate pre-treatment and prevent large nutrient ‘spikes' Landscape design, using appropriate plant species and planting density are also necessary.High costs of the planned pond/lake area and of vegetation establishment as well as frequent maintenance requirements can be deterrents to use of ponds and lakes as WSUD measures.
