Turtle River Lake FishingCWater-quality grade C
Minnesota DNR surveys at Turtle River Lake average 23.84 yellow perch per unit of sampling effort (CPUE) across 11 surveys. The most recent is a Targeted Survey dated August 10, 2023. Length samples in the latest survey that recorded them ran 4–9 inches. In Beltrami County, Minnesota, Turtle River Lake carries an overall water-quality grade of C. Water clarity averages 8.5 feet of visibility, and there are 2 public boat landings. 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.
Species recorded at Turtle River Lake
20 species on the Minnesota DNR list for this lake. A species on the list has been recorded here; it does not mean it is catchable today or in every part of the lake.
Stocking at Turtle River 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.

Minnesota DNR surveys at Turtle River Lake average 23.84 yellow perch per unit of sampling effort (CPUE) across 11 surveys. The most recent is a Targeted Survey dated August 10, 2023. Length samples in the latest survey that recorded them ran 4–9 inches.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Turtle River Lake C from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.
DNR Fisheries Survey Summary
11 surveys on file from MN DNR Fisheries. Most recent: 2023-08-10 (Targeted Survey).
Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|
| Yellow Perch | 23.84 | 0.13 lb |
| Bluntnose Minnow | 13.04 | — |
CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE means more abundant in standardized sampling. This is not a weekly bite report.
Length Distributions
Number of fish caught at each inch class in the most recent survey that recorded lengths. Red dashed line marks an approximate trophy threshold for that species.
Yellow Perch
From the 2023-08-10 survey
A temperature-dissolved oxygen profile was collected in three of the deepest basins on Turtle River Lake on August 10, 2023, to evaluate the amount of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee. Based on the profiles, the top of the thermocline (i.e., the location in…

Common questions
What fish are in Turtle River Lake?
Minnesota DNR surveys at Turtle River Lake average 23.84 yellow perch per unit of sampling effort (CPUE) across 11 surveys. The most recent is a Targeted Survey dated August 10, 2023. Length samples in the latest survey that recorded them ran 4–9 inches. Minnesota DNR lists 20 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 Turtle River Lake last surveyed?
The most recent fisheries survey on file for Turtle River Lake is dated August 10, 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 Turtle River Lake stocked?
Minnesota DNR publishes a stocking history for Turtle River 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 Turtle River Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Turtle River Lake C from EPA Water Quality Portal chemistry, and the water-quality trend over 6 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.
