Lab to Lakes

MAISRC launched the Lab to Lakes (L2L) initiative to move rigorously tested science into coordinated, on-the-ground implementation. Three priority projects are underway, focusing on managing common carp and invasive hybrid cattail, as well as establishing an environmental DNA (eDNA) testing lab to monitor multiple aquatic invasive species. By working with community partners on both management and monitoring, L2L projects translate rigorously tested science into coordinated, on-the-ground implementation.

Common carp

Cattail Collaborative

eDNA Lab

To manage common carp, MAISRC has partnered with local government units, to develop and execute research-driven carp management plans in two ecologically distinct systems: Lake Fremont and the Chisago Chain of Lakes. The objective is to reduce and sustainably maintain carp biomass below a damaging threshold to restore ecosystem function within four years. These efforts apply established population thresholds and monitoring frameworks to ensure that management actions contribute to sustained ecological recovery. 

MN Cattail Collaborative: The invasive hybrid cattail component of L2L scales up a research-validated removal protocol across 20-25 lakes across the state. Working alongside Minnesota Sea Grant and local partners, MAISRC researchers are establishing demonstration sites, training managers and volunteers in standardized monitoring and data collection, and evaluating how targeted cattail removal restores native plant communities. Genetic and field-based mapping will also quantify the extent of invasive hybrid cattail across Minnesota, addressing a critical knowledge gap.

The eDNA testing lab will allow MAISRC to support community partners with early detection of the presence of AIS. Currently, there are robust methods for eDNA detection of four high priority invasive species: common carp, rusty crayfish, spiny waterflea, and zebra mussels. These data will help research scientists create better models for invasion risk and will give managers more information that can help with their management goals for aquatic invasive species.

Together, these coordinated efforts exemplify Lab to Lakes’ guiding mission: management decisions should be grounded in research, have clear ecological benchmarks, and transparent data. By pairing applied science with collaborative implementation, MAISRC is delivering practical, field-tested guidance that lake managers, communities, and policymakers can use to restore and protect Minnesota’s waters.
