In 2022, USGS pumped red dye into California’s Keswick Reservoir for 4.5 hours to track water from a Superfund mine; currents crept just one meter every 20–100 seconds

Researchers conducted an intriguing experiment in April 2022 by releasing a nontoxic red dye into Keswick Reservoir. This initiative aimed to study how water from the Spring Creek system blended into the reservoir. Using advanced submerged instruments and GPS drifters, they meticulously monitored the dye’s trajectory, while a three-dimensional model integrated field data, improving comprehension of contaminant dilution in waters downstream of Iron Mountain Mine.
