A statistical analysis of water quality data from Lake Vänern spanning three decades has been performed in order to establish an appropriate level of complexity for a water quality model. The analysis consists of paired t-tests for differences in the vertical direction and multiple comparison tests (Tukey's honestly significant difference criterion) for differences in the horizontal direction. The analysis indicates significant differences between the epi- and hypolimnion during stratified periods, but no significant differences in mixed periods. The two distinct basins are only marginally different. Furthermore, each basin can be considered well-mixed horizontally, except for parts located close to point emissions, or the particularly shallow regions.
