Abstract
Constructed waterbodies serve a variety of purposes. Urban lakes are a contemporary constructed waterbody, which often serve to increase amenity and property values, fulfill a flood mitigation purpose, and may provide a source of land fill for development purposes. Although popular, urban lakes have degraded in many areas as a result of: (1) poor quality of inflow; (2) significant water level variation; (3) persistent stratification; (4) long stormwater residence times; and (5) high loading of organic carbon. The failure of many urban lakes to remain as a resilient and healthy ecosystem stems from poor design and a lack of pretreatment to runoff. Recent design guidelines have better informed designers as to the key design elements for urban lakes; however, management of these waterbodies remains reactive, rather than proactive. Utilizing the Ecosystem Health Paradigm as a template for urban lake management may allow for a more holistic assessment of urban lake health and better inform management requirements. This chapter looks at the history of urban lakes and how such systems are integrated and managed in the urban context
