Deep Lake FishingCWater-quality grade C
Minnesota DNR surveys at Deep Lake average 1.86 walleye per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated July 12, 1995. Length samples in the latest survey that recorded them ran 12–25 inches. In Ramsey County, Minnesota, Deep Lake carries an overall water-quality grade of C. Water clarity averages 3.9 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.
Species recorded at Deep Lake
19 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 Deep Lake
No stocking record for Deep Lake appears in the Minnesota DNR material on file. That is an absence in the published record, not a confirmation that the lake is unstocked — some waters are managed as naturally reproducing and never appear in a stocking list at all.
Survey results in full
Minnesota DNR surveys at Deep Lake average 1.86 walleye per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated July 12, 1995. Length samples in the latest survey that recorded them ran 12–25 inches.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Deep Lake C 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.
DNR Fisheries Survey Summary
3 surveys on file from MN DNR Fisheries. Most recent: 1995-07-12 (Standard Survey).
Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |

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.

From the 1995-07-12 survey
Sunfish and crappies dominated the catch, with black crappie and bluegill the most abundant. Moderate numbers of walleye, northern pike, channel catfish, muskellunge, and bowfin were present. Low numbers of largemouth bass, carp, white bass, yellow perch, bigmouth buffalo, black bullhead, golden shiner, and shorthead…

Common questions
What fish are in Deep Lake?
Minnesota DNR surveys at Deep Lake average 1.86 walleye per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated July 12, 1995. Length samples in the latest survey that recorded them ran 12–25 inches. Minnesota DNR lists 19 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 Deep Lake last surveyed?
The most recent fisheries survey on file for Deep Lake is dated July 12, 1995. 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 Deep Lake stocked?
No stocking record for Deep Lake appears in the Minnesota DNR material on file. That is not the same as a confirmed unstocked lake: it means no stocking document was published for it in the records this page draws on.
Does the water-quality grade tell me how Deep Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Deep Lake C 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.
