Winchell

Temperature and dissolved oxygen measurements were collected in the deepest basin in Winchell Lake, on August 21, 2024, 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 (Cisco, also known as Tullibee, are present). 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, the water temperature dropped below 8.8 degrees C (47.8 degrees F) at 39.4 feet, and the dissolved oxygen concentration never decreased to below 3.0 mg/L at the time of sampling. The thickness of this layer in the water column was 108.2 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 never reached because the dissolved oxygen remained above 3.0 mg/L throughout the sampled depths. The temperature at the bottom of the lake was 6.6 degrees C (43.9 degrees F). Instances in which the dissolved oxygen does not reach below 3.0 mg/L and temperature remains below 8.8 degrees C, indicate that oxythermal conditions were suitable for Lake Trout at the time of the survey. Data collected by the Minnesota Department of Natural Resources in 2023 during the late summer thermal stress period indicated suitable oxythermal habitat. Data were also collected outside the thermal maximum period from 1981-2012, this data indicated suitable habitat conditions during those sampling periods. The least favorable oxythermal habitat conditions were recorded in 1992, outside the peak summer stress period, when the suitable habitat layer thickness was 51.4 feet. When inadequate oxythermal habitat is available, Lake Trout are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.

Winchell has a maximum depth of 160 feet, per Minnesota DNR data.

The most recent Minnesota DNR survey data for the main sport fish in Winchell is from 2012. Surveys this old should be treated with some caution — fish populations change over time.

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