1988 Dye Experiment Reveals Hidden Layered Currents in Canadian Lake
A 1988 scientific experiment using colored dyes at a Canadian lake revealed hidden layered circulation patterns, showing that deeper water can move in the opposite direction of surface winds.

In August 1988, researchers studying water circulation patterns conducted an experiment at Twin West Lake, located approximately 75 kilometres east of Vancouver, Canada.
To track movement during the study, scientists released green sodium fluorescein and red Rhodamine WT dyes into the water. The setup utilized 14 marker buoys arranged on a 60-metre grid and cameras that captured images every two minutes.
The research revealed a layered circulation pattern within the lake. Water near the surface moved with the wind at an average speed of 2.8 centimetres per second, while water deeper in the epilimnion moved in the opposite direction at approximately 1 centimetre per second.
The findings were published in the journal Limnology and Oceanography. The data detailed how stratification and wind influence the transport of nutrients and pollutants in lakes.
