Gibson

Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in Gibson Lake on July 31st, 2025, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee, the most sensitive coldwater species present in this lake. During the summer, Cisco require a layer of oxythermal habitat that contains water temperatures below 21.2 degrees C (70.2 degrees F) and dissolved oxygen concentrations above 3.0 mg/L. Based on the profile from the deepest basin (maximum sampled depth 19.7 feet), the water temperature never decreased below 21.2 degrees C (70.2 degrees F) and the dissolved oxygen concentration stayed greater than 3.0 mg/L throughout the entire sampled depth. Therefore, the water column did not contain a layer of water with sufficient temperature and dissolved oxygen for Cisco. 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 dissolved oxygen remained above 3.0 mg/L throughout the sampled depths. In this case, the minimum temperature, 23.2 degrees C (73.8 degrees F), was substituted as TDO3. TDO3 values warmer than 21.2 degrees C (70.2 degrees F) indicate that oxythermal conditions were unsuitable for Cisco 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 2024 also indicates unsuitable oxythermal habitat. When adequate oxythermal habitat is unavailable, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.

Based on Minnesota DNR survey data, anglers target Yellow Perch, Northern Pike, and Walleye in Gibson. See the full species list above for catch rates, size structure, and quality scores.

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

Gibson has a maximum depth of 24 feet, per Minnesota DNR data.

The most recent Minnesota DNR survey data for the main sport fish in Gibson is from 1982. Surveys this old should be treated with some caution — fish populations change over time.

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