In 2026, the Minnesota Department of Natural Resources (DNR) will study aquatic invertebrates in Bryant Lake.

Learning more about aquatic invertebrates in Bryant Lake!

Aquatic invertebrates include a diverse group of animals ranging from microscopic zooplankton that drift in open water to larger organisms like insect larvae, snails, crayfish, and mussels that are found on rocks, logs, and aquatic plants. These animals play an important role in nutrient cycling, controlling algae, and provide food for fish and wildlife.

Where are the sampling sites located?

There are four sampling sites located on the north and south side of the lake.

See map for approximate locations.

What does a sampling site look like?

At each sampling site, DNR staff have installed 4 plastic trays (takeout container sized) in 1-2 feet of water near the lakeshore. The trays are placed on undeveloped/natural shoreline and out of the way of boat traffic and other recreational use. The trays are wedged in sand to stay secure and are marked with a stake to help researchers relocate the trays. During open water season, staff will pull and replace the trays every 1 to 2 months to collect data on macroinvertebrate diversity and quantity.

For researchers to gather accurate information on the invertebrates, it is important that the trays are not disturbed or moved.

Please do not disturb the sampling trays!

Plastic trays submerged in water with a marking stick and and pink flag to indicate a sampling site. pink tape, will be placed in the sand in shallow water to monitor aquatic macroinvertebrate populations.

How long will the study last?

The study will take place in 2026 and may continue through 2027 pending approval. Staff will visit the trays every 1 to 2 months during the open water season.
