Influences of local and watershed factors on lake water 
properties were discussed with special emphasis on 
factors which can be assessed by remote sensing. First 
investigations of possible relationships show the 
importance of local parameters reflecting conditions of 
lake genesis for the differentiation of lake water 
properties, whereas landuse of the surroundings 
seems to be a factor of secondary importance. 
Further investigations are directed towards a 
systematic analysis of the importance of individual 
factors influencing trophic state conditions. Additionally, 
the multitemporal satellite data will be evaluated more 
detailed for of a better understanding of the spatial and 
temporal variations of the lake water properties.
