Minnesota removed common carp; lake clarity rose nearly 600% afterward

Pickerel Lake, Minnesota, has battled significant water quality and algal bloom problems for decades, primarily due to invasive common carp taking over the shallow waters.

After their removal in 2009, the lake underwent a remarkable ecological revival, with water clarity significantly improving and native aquatic plants flourishing once more.

This successful restoration highlights the pivotal role of addressing invasive species in revitalizing ecosystems.
