Summary

Story summary

The new research shows beaver ponds influence groundwater dynamics in Colorado's Rocky Mountains, with dam-building spreading water and seeping it to recharge aquifers.
Water from these ponds may flow downstream through hidden channels.
The study notes risks, as anaerobic bacteria in beaver ponds can release heavy metals from sediment in polluted areas.
Beaver activity offers ecological benefits but creates trade-offs for water quality.
