From the 2023-10-23 survey
A survey targeting age-0 Walleye was conducted at Roberds Lake on 23 October 2023 using 56 minutes of standard boat electrofishing. Zero age-0 Walleye were sampled for a catch rate of 0.0/hour on-time. Catch rates have averaged 3.1/hour on-time during 7 surveys since 2017. During that period non-stocked years (n = 4)…

Common questions
What fish are in Roberds Lake?
Minnesota DNR surveys at Roberds Lake average 3856.08 largemouth bass per unit of sampling effort (CPUE) across 14 surveys. The most recent is a Targeted Survey dated October 23, 2023. Length samples in the latest survey that recorded them ran 6–18 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 Roberds Lake last surveyed?
The most recent fisheries survey on file for Roberds Lake is dated October 23, 2023. 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 Roberds Lake stocked?
Minnesota DNR publishes a stocking history for Roberds 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 Roberds Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Roberds Lake F from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is stable. 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.
