Why Fourteen Lake has no grade
We grade a lake only when the monitoring record supports a letter: at least three phosphorus or chlorophyll-a samples in the last ten years, scored against EPA National Lakes Assessment thresholds for this lake’s ecoregion. For Fourteen Lake, the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Sampling here has recorded water clarity, but not phosphorus and algae (chlorophyll-a).
Not Rated is not an F. It is EPA Integrated Reporting Category 3 — insufficient information. The water here may be excellent or poor; nobody has measured enough of it to say. Everything below that has been measured is still reported on this page.
Sampling is run by MPCA and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Fourteen Lake is a 386-acre lake in St. Louis County, Minnesota with a maximum depth of 15 feet. Overall water quality is improving over recent sampling years. The lake supports 7 documented fish species including black crappie, bluegill, and hybrid sunfish. No public access — the lake is private or restricted.

Minnesota DNR surveys at Fourteen Lake average 5.27 northern pike per unit of sampling effort (CPUE) across 7 surveys. The most recent is a Standard Survey dated June 14, 2010. Length samples in the latest survey that recorded them ran 14–34 inches.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Fourteen Lake — official chemistry is on file, not a letter, 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
7 surveys on file from MN DNR Fisheries. Most recent: 2010-06-14 (Standard Survey).
Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|
| Bluegill | 23.67 | 0.26 lb |
| Pumpkinseed | 9.68 | 0.15 lb |
| Northern Pike | 5.27 | 2.33 lb |
| Brown Bullhead | 3.86 | 1.38 lb |
| Yellow Perch | 3.35 | 0.16 lb |
| Black Crappie | 2.85 | 0.37 lb |
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.
