Stocking at Blue 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.
Survey results in full
Minnesota DNR's Standard Survey on July 12, 1982 caught 10.17 northern pike per gill net at Blue Lake.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Blue Lake’s water-quality measurements separately, 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.

From the 1982-07-12 survey
Yellow bullheads and sunfish are presently abundant. Tullibee population has apparently disappeared. Northern pike have increased considerably since last survey. Yellow perch seem to be present in approximately the same numbers.

Common questions
What fish are in Blue Lake?
Minnesota DNR's Standard Survey on July 12, 1982 caught 10.17 northern pike per gill net at Blue Lake. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Blue Lake last surveyed?
The most recent fisheries survey on file for Blue Lake is dated July 12, 1982. 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 Blue Lake stocked?
Minnesota DNR publishes a stocking history for Blue 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.
Do the water-quality readings tell me how Blue Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Blue Lake’s water-quality measurements separately, 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
Water-quality readings are 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 with clear, low-nutrient water can still carry a meal limit on larger predator fish.
