Gaskin

Temperature and dissolved oxygen measurements were collected in the deepest basin in Gaskin 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 (Lake Whitefish and Cisco also 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 36.1 feet, and the dissolved oxygen concentration never decreased to below 3.0 mg/L at the time of sampling. The thickness of this layer of water in the water column was 19.7 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 7.1 degrees C (44.8 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 from 1990-2023 during the late summer thermal stress period indicated suitable oxythermal habitat in years surveyed, with the least favorable conditions recorded in 2012 when the suitable habitat layer thickness was 6.3 feet. When inadequate oxythermal habitat is available, Lake Trout are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.

Gaskin has a maximum depth of 82 feet, per Minnesota DNR data.

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

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