South Sugar Lake FishingAWater-quality grade A
Minnesota DNR surveys at South Sugar Lake average 28.66 largemouth bass per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated August 21, 2017. Length samples in the latest survey that recorded them ran 8–18 inches. In Itasca County, Minnesota, South Sugar Lake carries an overall water-quality grade of A.

Neither is a forecast of today's bite.
Species recorded at South Sugar Lake
8 species on the Minnesota DNR list for this lake. A species on the list has been recorded here; it does not mean it is catchable today or in every part of the lake.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades South Sugar Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in South Sugar Lake?
Minnesota DNR surveys at South Sugar Lake average 28.66 largemouth bass per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated August 21, 2017. Length samples in the latest survey that recorded them ran 8–18 inches. Minnesota DNR lists 8 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 South Sugar Lake last surveyed?
The most recent fisheries survey on file for South Sugar Lake is dated August 21, 2017. 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 South Sugar Lake stocked?
No stocking record for South Sugar 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 South Sugar Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades South Sugar Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is declining. 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.
