Short summary

Lake models are powerful tools for disentangling complex past climate data preserved in sediments. These models can be hard to set-up for lakes that are not well-observed. We improve an existing model with code to simulate water runoff and establish guidelines for setting-up the model when data are scarce. Using our workflow, more scientists can apply this tool to more lakes and gain a better understanding of the climate histories stored in their sediments.
