A group of researchers published a paper in March 2023 regarding the effects of stream drying on the Blue River’s ecosystem, and found that “connectivity can decrease drastically with only small changes in daily streamflow.”

Here are some excerpts from the research:

Habitat fragmentation drives biodiversity loss in rivers around the world.

We observed that [Blue River] connectivity can decrease drastically with only small changes in daily streamflow. The slope of the modeled relationship between streamflow and DCI indicates the presence of a threshold in the Upper Blue River Basin between daily streamflow values of 105 and 106 m3/day.

The watershed tended to be well connected when the daily streamflow was above this threshold and more poorly connected when the daily streamflow was below the threshold.
