Baby

Temperature and dissolved oxygen profiles were collected in the deepest basins in Baby Lake on July 31, 2024, 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. 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, the water temperature decreased to below 21.2 degrees C (70.2 degrees F) at 20.0 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 20.1 feet at the time of sampling. The thickness of this layer of water in the water column was 0.1 feet, indicating that limited oxythermal habitat was present 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 21.1 degrees C (70.0 degrees F). TDO3 values near 21.2 degrees C (70.2 degrees F) indicate that oxythermal conditions were marginal for Cisco; however, the layer was confined to less than 3 feet of suitable habitat at the time of this survey. Data collected by the Minnesota Department of Natural Resources in 2022 and 2023 during the late summer thermal stress period indicate suitable oxythermal habitat, with the least favorable conditions recorded in 2022. When inadequate oxythermal habitat is available, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.

Based on Minnesota DNR survey data, anglers target Smallmouth Bass, Walleye, Muskellunge, Black Crappie, and Northern Pike in Baby. See the full species list above for catch rates, size structure, and quality scores.

Minnesota DNR records list public access for Baby. Check the DNR LakeFinder page for the launch type and directions before you go.

Baby has a maximum depth of 69 feet and a mean depth of 31 feet, per Minnesota DNR data.

The most recent Minnesota DNR survey data for the main sport fish in Baby is from 2024.

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

No — Baby has no lake-specific regulations in the 2026 Minnesota DNR regulations, so statewide Minnesota limits apply. The statewide walleye and sauger limit is: 6 combined, not more than one walleye over 20". Verify current rules with the Minnesota DNR before keeping fish.
