Zimbabwe’s water resources are under pressure from both point and non-point sources of pollution
hence the need for regular and synoptic assessment. In-situ and laboratory based methods of water quality monitoring
are point based and do not provide a synoptic coverage of the lakes. This paper presents novel methods for
retrieving water quality parameters in Chivero and Manyame lakes, Zimbabwe, from remotely sensed imagery.
Remotely sensed derived water quality parameters are further validated using in-situ data. It also presents an application
for automated retrieval of those parameters developed in VB6, as well as a web portal for disseminating
the water quality information to relevant stakeholders. The web portal is developed, using Geoserver, open layers
and HTML. Results show the spatial variation of water quality and an automated remote sensing and GIS system
with a web front end to disseminate water quality information.
