Carp Assessments
Le Sueur County completed carp assessments in the summer of 2019. The intent of completing these assessments is to have a better understanding of the total biomass of carp that exist within each lake.
At the time of sampling, the common carp populations present in 9 out of the 11 sites (82%) were estimated to be exceeding the biomass density threshold known to be problematic to water quality (89 lbs/acre). Estimated biomass densities varied from 3-12 times the impact threshold of 89 pounds per acre, with approximately 400,000 individuals estimated to exist between the 11 lakes sampled.
The next steps for the Le Sueur County is to collect more data and research in order to make future decisions about common carp populations.
