Abstract The water quality data collected on the ground by the Water District Office in Oulu was subjected to statistical analyses together with Landsat data to display a few interactions and the possibilities of exploiting remote sensing methods in water area surveying. Correlations between the Landsat data statistics and some water quality measurements were identified. The small size of the studied lakes does not allow any clear calibration to be made but there could be possibilities to develop remote sensing methods for the evaluation of environmental variables and the detection of productivity and the eutrophication stage. The remote sensing procedure could also be useful in portraying temporal variations within lakes as well as relative variations between lakes by classifying each lake on a pixel-by-pixel basis. Although the remote sensing method is not able to supersede ground truth information for lake studies, it has value in regions where many lakes are to be found within a restricted small area. Under these circumstances the collection of information on the ground for a small number of test lakes and the generalization of this data, with the aid of machine-pressing remote sensing, would result in considerably less field work and cost savings.
