Missouri River dye test tracked plume 41.2 miles and measured 8.2-hour delay

Scientists recently conducted a dye-tracing experiment on the Missouri River in Montana to analyze the movement of substances through the waterway. The study successfully tracked a dye plume across a distance of 41.2 miles, revealing an 8.2-hour delay in its progression along the river's path.

The research examined how substances disperse through various sections of the river and its associated reservoirs. By measuring the plume's spread and its varying speeds across different segments, the study provides data on the hydraulic characteristics of the Missouri River system.
