Minnesota DNR surveys at Rush Lake average 36.96 walleye per unit of sampling effort (CPUE) across 18 surveys. The most recent is a Targeted Survey dated October 3, 2024. Length samples in the latest survey that recorded them ran 6–22 inches. In Sherburne County, Minnesota, Rush Lake carries an overall water-quality grade of F. Water clarity averages 2.0 feet of visibility, and there is one public boat landing. 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.

Night electrofishing was conducted during the evening of October 3, 2024. A total of nine young of year (YOY) Walleye were collected…

Common questions
What fish are in Rush Lake?
Minnesota DNR surveys at Rush Lake average 36.96 walleye per unit of sampling effort (CPUE) across 18 surveys. The most recent is a Targeted Survey dated October 3, 2024. Length samples in the latest survey that recorded them ran 6–22 inches. Minnesota DNR lists 18 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 Rush Lake last surveyed?
The most recent fisheries survey on file for Rush Lake is dated October 3, 2024. 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 Rush Lake stocked?
Minnesota DNR publishes a stocking history for Rush 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 Rush Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Rush 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.
