Little Andrus Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Little Andrus Lake average 6.37 brook trout per unit of sampling effort (CPUE) across 15 surveys. The most recent is a Targeted Survey dated August 18, 2022. Length samples in the latest survey that recorded them ran 9–17 inches. In Cass County, Minnesota, Little Andrus Lake has no letter grade — the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Water clarity averages 13.0 feet of visibility, and the lake has public access. The survey figures on this page are Minnesota DNR's own; the water-quality grade comes from EPA Water Quality Portal samples. Neither is a forecast of today's bite.
Stocking at Little Andrus Lake
Minnesota DNR publishes a stocking history for this lake — which species went in, how many, and in which years. Read the years: a lake stocked in one year is not necessarily stocked in the next.

DNR Fisheries Survey Summary
15 surveys on file from MN DNR Fisheries. Most recent: 2022-08-18 (Targeted Survey).
Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|
| Fathead Minnow | 246.67 | — |
| Brook Trout | 6.37 | 0.66 lb |
CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE means more abundant in standardized sampling. This is not a weekly bite report.
Length Distributions
Number of fish caught at each inch class in the most recent survey that recorded lengths. Red dashed line marks an approximate trophy threshold for that species.
Brook Trout
From the 2022-08-18 survey
Snowshoe (Little Andrus) Lake is a designated stream trout lake that is managed for Brook Trout. The dissolved oxygen and temperature profiles were measured in August 2022 to monitor habitat for trout. Optimal thermal and oxygen conditions for Brook Trout (10-16°C [50-61°F] and greater than or equal to 5 ppm DO)…

Common questions
What fish are in Little Andrus Lake?
Minnesota DNR surveys at Little Andrus Lake average 6.37 brook trout per unit of sampling effort (CPUE) across 15 surveys. The most recent is a Targeted Survey dated August 18, 2022. Length samples in the latest survey that recorded them ran 9–17 inches. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Little Andrus Lake last surveyed?
The most recent fisheries survey on file for Little Andrus Lake is dated August 18, 2022. Survey intervals vary by lake and by species; a gap of several years between surveys is normal and does not mean the record is missing.
Is Little Andrus Lake stocked?
Minnesota DNR publishes a stocking history for Little Andrus Lake. It records which species were released, in what numbers and in which years — the source documents are linked further down this page. A lake can be stocked in some years and not others, so read the years rather than assuming an annual release.
Does the water-quality grade tell me how Little Andrus Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Little Andrus Lake — official chemistry is on file, not a letter. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
A water-quality grade is not a consumption advisory. Mercury and PCB advice for Minnesota waters comes from MDH, and it is issued per species and per size class — a lake can grade well and still carry a meal limit on larger predator fish.
