Mora Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Mora Lake average 4.75 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated June 24, 1986. In Kanabec County, Minnesota, Mora 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 5.0 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 Mora 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 surveys at Mora Lake average 4.75 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated June 24, 1986.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Mora Lake — official chemistry is on file, not a letter, and the water-quality trend over 2 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Mora Lake?
Minnesota DNR surveys at Mora Lake average 4.75 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated June 24, 1986. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Mora Lake last surveyed?
The most recent fisheries survey on file for Mora Lake is dated June 24, 1986. 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 Mora Lake stocked?
Minnesota DNR publishes a stocking history for Mora 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 Mora 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 Mora Lake — official chemistry is on file, not a letter, and the water-quality trend over 2 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.
