Length samples in the latest survey that recorded them ran 4–18 inches. In Hubbard County, Minnesota, Lasalle Lake carries an overall water-quality grade of A.

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.
Species recorded at Lasalle Lake

From the 2025-08-05 survey
Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in LaSalle Lake on August 5th, 2025, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee, the most sensitive coldwater species present in this lake.…

Common questions
What fish are in Lasalle Lake?
Minnesota DNR surveys at Lasalle Lake average 6.44 largemouth bass per unit of sampling effort (CPUE) across 6 surveys. The most recent is a Targeted Survey dated August 5, 2025. Length samples in the latest survey that recorded them ran 4–18 inches. Minnesota DNR lists 15 species for the lake in total. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Lasalle Lake last surveyed?
The most recent fisheries survey on file for Lasalle Lake is dated August 5, 2025. 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 Lasalle Lake stocked?
No stocking record for Lasalle Lake appears in the Minnesota DNR material on file. That is not the same as a confirmed unstocked lake: it means no stocking document was published for it in the records this page draws on.
Does the water-quality grade tell me how Lasalle Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Lasalle Lake A from EPA Water Quality Portal chemistry. 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.
