Partridge

Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in Partridge Lake on August 11th, 2025, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Trout, the most sensitive coldwater species present in this lake. During the summer, Lake Trout require a layer of oxythermal habitat that contains water temperatures below 8.8 degrees C (47.8 degrees F) and dissolved oxygen concentrations above 3.0 mg/L. Based on the profile from the deepest basin (maximum sampled depth 80 feet), the water temperature decreased below 8.8 degrees C (47.8 degrees F) at 26.1 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 60.0 feet at the time of sampling. The thickness of this layer of water in the water column was 34.0 feet, indicating that oxythermal habitat was present for Lake Trout. Further, the temperature at which dissolved oxygen decreased to 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 6.0 degrees C (42.8 degrees F). TDO3 values cooler than 8.8 degrees C (47.8 degrees F) indicate that oxythermal conditions were suitable for Lake Trout at the time of the survey. Data collected by the Minnesota Department of Natural Resources during the late summer period of maximum oxythermal stress (July 26th to Aug 24th) in 2023, 2024, 1970 also indicate suitable oxythermal habitat in all years surveyed. When adequate oxythermal habitat is unavailable, Lake Trout are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.

We don't have a confirmed public access point on record for Partridge. Check the DNR LakeFinder page for current access details before you go.

Partridge has a maximum depth of 80 feet and a mean depth of 35 feet, per Minnesota DNR data.

The most recent Minnesota DNR survey data for the main sport fish in Partridge is from 2018. Surveys this old should be treated with some caution — fish populations change over time.

No invasive species are on record for Partridge in Minnesota DNR data. Always clean, drain, and dry your equipment to help keep it that way.
