Length samples in the latest survey that recorded them ran 13–19 inches. In Polk County, Minnesota, Store Lake carries an overall water-quality grade of F. Water clarity averages 6.9 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 Store 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.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Store Lake F from EPA Water Quality Portal chemistry, and the water-quality trend over 5 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2009-08-03 survey
Store (Peterson) Lake is a 52-acre, eutrophic lake in eastern Polk county that is currently vulnerable to winterkill. The lake and its fish community have undergone dramatic changes since it was first surveyed in 1983. At the time of the 1983 survey, Store was not considered a winterkill lake. Water clarity was good…

Common questions
What fish are in Store Lake?
Minnesota DNR surveys at Store Lake average 1.56 walleye per unit of sampling effort (CPUE) across 4 surveys. The most recent is a Standard Survey dated August 3, 2009. Length samples in the latest survey that recorded them ran 13–19 inches. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Store Lake last surveyed?
The most recent fisheries survey on file for Store Lake is dated August 3, 2009. 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 Store Lake stocked?
Minnesota DNR publishes a stocking history for Store 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 Store Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Store Lake F from EPA Water Quality Portal chemistry, and the water-quality trend over 5 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.
