Cedar Lake is a 164-acre productive, nutrient-rich eutrophic lake in Hennepin County, Minnesota with a maximum depth of 51 feet. Overall water quality is improving over recent sampling years. The lake supports 15 documented fish species including black bullhead, black crappie, and bluegill. No public access — the lake is private or restricted. Compared to the 80 other monitored lakes in Hennepin County, Cedar Lake ranks #30 for water quality.

Swimming conditions

Readings only

Bacteria tested: low

Based on clarity and algae readings from past sampling — there is no live water temperature and a current cyanobacteria reading for this lake. Check your state or county health department before you swim.

Bacteria testing record
from E. coli testing · 6 samples, 6 seasons

Based on E. coli testing, Cedar Lake never exceeded the EPA safe-swimming threshold (235 MPN/100mL) — on 0% of 6 samples across 6 seasons.

This is a historical summary of past testing, not a current condition — bacteria levels change quickly, especially after rain. Always check Minnesota’s current beach and health-department advisories before swimming.

Whether Cedar Lake is safe to swim in today is a call for the Minnesota Pollution Control Agency and the Minnesota DNR and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.

DNR fisheries survey

Minnesota DNR's Standard Survey on July 8, 2024 caught 6.00 northern pike per gill net at Cedar Lake. Length samples in the latest survey that recorded them ran 13–29 inches.

A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Cedar Lake’s water-quality measurements separately, 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.
