From Wisconsin DNR / Citizen Lake Monitoring readings at Durphee Lake - Deep Hole.
Last sampled Sep 2024
Through 2024, low nutrients in the most recent monitored summers.
Based on July–August 2024 averages across 3 volunteer readings.NutrientsTotal phosphorus — fuels plant & algae growth

LowStable since 2014
Low phosphorus means light plant/algae growth pressure.
No recent clarity readings — last measured 2015. No recent algae readings — last measured 2015.

Latest individual samples: Secchi 6 ft (2015-08-31), chlorophyll-a 11 µg/L (2015-08-31), and total phosphorus 25 µg/L (2024-09-04).
Secchi clarity is how deep a black-and-white disk stays visible from the surface — more feet means clearer water.
Chlorophyll-a is an algae pigment; higher values signal more algae in the water column.
Total phosphorus is a nutrient that feeds algae and aquatic plants. It is not a weed survey — depth, bottom type, water movement, and management change the actual lake experience.

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2021 DNR fisheries survey. Population estimates, density, and catch-rate indices use different units, methods, and scopes, so each value is presented in its original form rather than normalized against a different measure.
Survey indicatorsValues keep their source unit and method; unlike measures are not scaled or compared.
Management contextThe 2021 survey assessed Durphee Lake (WBIC 2396800) only; the source explicitly excludes connected Schoolhouse Lake from sampling, so every promoted metric retains Durphee-only population scope.

Depth FAQ
How deep is Durphee Lake?
Durphee Lake is 16 feet deep at its deepest point and averages about 10 feet, according to Wisconsin DNR records.
Is there a free depth map of Durphee Lake?
Yes. LakeList publishes a free interactive depth contour map of Durphee Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Durphee Lake depth map come from?
The interactive depth contours are derived from C-MAP Genesis community sonar (derived). Each contour set passes a visual QA review against the source document before it is published. The depths are derived from community sonar recordings (C-MAP Genesis Social Map, used with permission), with gaps between recordings interpolated; not for navigation.
