Lake levels have fluctuated and lake depths changed through the Holocene reflecting regional climate variations and sediment accumulation. Cladoceran remains preserved in sediments have been widely used for qualitative (P/L ratio) and quantitative (inference models) lake-depth reconstructions. In addition to estimations of prediction errors for performance power of modern data sets, it is important also to evaluate the reliability of reconstructed environmental values and to ensure that they are ecologically and paleoclimatically meaningful. In this study, we reconstructed the Holocene lake-depth history of a northern boreal lake using the Cladocera P/L ratio and a Cladocera—lake-depth inference model. These results were evaluated by comparison with reconstructions based on other proxies (aquatic macrofossils, sediment composition and sedimentation pattern) derived from three radiocarbon-dated sediment cores from the same lake. Whilst the reconstructions based on Cladocera and on the combination of other proxies yielded similar long-term trends, the absolute water depth values derived from the quantitative cladoceran model deviated from what was indicated by the other proxies. Therefore, we strongly recommend that also other, independent methods should be used simultaneously when reconstructing past water depths using Cladocera remains.
