Link Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Link Lake average 2.00 northern pike per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Targeted Survey dated July 31, 2025. In Lake County, Minnesota, Link Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Water clarity averages 10.0 feet of visibility. 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 Link Lake
No stocking record for Link Lake appears in the Minnesota DNR material on file. That is an absence in the published record, not a confirmation that the lake is unstocked — some waters are managed as naturally reproducing and never appear in a stocking list at all.
Survey results in full
Minnesota DNR surveys at Link Lake average 2.00 northern pike per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Targeted Survey dated July 31, 2025.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Link Lake — official chemistry is on file, not a letter, and the water-quality trend over 5 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

3 surveys on file from MN DNR Fisheries. Most recent: 2025-07-31 (Targeted Survey).
Top Species by Catch Rate

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.
From the 2025-07-31 survey
Temperature and dissolved oxygen measurements were collected from the deepest basin in Link Lake on July 31st, 2025. This was done to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Whitefish, the most sensitive coldwater species present in this lake. Lake…

Common questions
What fish are in Link Lake?
Minnesota DNR surveys at Link Lake average 2.00 northern pike per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Targeted Survey dated July 31, 2025. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Link Lake last surveyed?
The most recent fisheries survey on file for Link Lake is dated July 31, 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 Link Lake stocked?
No stocking record for Link 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 Link 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 Link Lake — official chemistry is on file, not a letter, and the water-quality trend over 5 years of monitoring is improving. 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.
