Throughout summer 2026, volunteers collected environmental DNA samples from 52 Minnesota lakes to screen for invasive zebra mussels. This research-stage effort aims to establish an early warning system for species that currently infest approximately 5 percent of the state's lakes.

Why it matters

Early detection of zebra mussels is critical for protecting Minnesota ecosystems, as these organisms consume plankton and clog water infrastructure. Identifying new infestations allows managers to implement control measures before a population becomes widespread.

Volunteers pump water through filters, which are then analyzed at a St. Paul laboratory for zebra mussel genetic signatures. While this process identifies presence or absence, it currently lacks the capability to estimate total population size.

The players

University of Minnesota Aquatic Invasive Species Center

A research entity focused on the detection and management of invasive species within the state's waterways.

The details

The environmental DNA (eDNA) detection method involves filtering lake water through a membrane that traps biological material shed by aquatic organisms. Researchers at the University of Minnesota Aquatic Invasive Species Center then process these samples to isolate genetic sequences unique to the invasive mussel. This technique allows for the identification of the species even at very low concentrations in the water column.

Timeline

  1. Summer 2026: Volunteers collected eDNA samples from 52 Minnesota lakes.

  2. October 2026: Laboratory testing of the water samples will begin.

  3. December 2026 - January 2027: Results will be released to volunteers and lake managers.

  4. Summer 2027: The research center intends to distribute additional test kits.

The Tech Race

This project scales the University of Minnesota Aquatic Invasive Species Center's monitoring program through decentralized volunteer collection. It represents a shift toward low-cost, high-volume environmental surveillance in the race to contain aquatic invasive species.

Residents and lake managers near sites like Clear Lake will receive specific data on zebra mussel presence by early 2027. Future testing availability will expand next summer as the research center scales its distribution of citizen-use test kits.

The takeaway

This project highlights the potential of citizen science to increase the geographic coverage of invasive species monitoring. Interested participants should monitor the University of Minnesota Aquatic Invasive Species Center website for updates on 2027 kit distribution and program expansion.

What happens next

Results from the 52 lake samples are expected to be available for review by lake managers and participating volunteers between December 2026 and January 2027.
