Twin Lake FishingDWater-quality grade D
Minnesota DNR surveys at Twin Lake average 5.49 northern pike per unit of sampling effort (CPUE) across 7 surveys. The most recent is a Standard Survey dated June 11, 2018. Length samples in the latest survey that recorded them ran 19–33 inches. In Hennepin County, Minnesota, Twin Lake carries an overall water-quality grade of D. Water clarity averages 5.9 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.
Species recorded at Twin Lake
13 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 Twin 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.

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 2018-06-11 survey
Twin Lake is a 217-acre lake in Hennepin County. Twin Lake consists of three distinct basins that are connected by navigable channels. Although this survey treats the lake as one waterbody, the three basins are different from one another. The south and middle basins have less algae and vegetation, with maximum depths…

Common questions
What fish are in Twin Lake?
Minnesota DNR surveys at Twin Lake average 5.49 northern pike per unit of sampling effort (CPUE) across 7 surveys. The most recent is a Standard Survey dated June 11, 2018. Length samples in the latest survey that recorded them ran 19–33 inches. Minnesota DNR lists 13 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 Twin Lake last surveyed?
The most recent fisheries survey on file for Twin Lake is dated June 11, 2018. 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 Twin Lake stocked?
Minnesota DNR publishes a stocking history for Twin 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 Twin Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Twin Lake D from EPA Water Quality Portal chemistry, and the water-quality trend over 4 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.
