What aquatic invasive species are found in Bertha Lake?
Join us in the fight to prevent the spread of invasive species These sneaky creatures can hitch a ride on boats, clinging onto propellers, anchor lines, and trailers. They can even survive in hidden places like bilge water and ballast tanks, or disguise themselves in dirt and sand that sticks to nets, buckets, anchors, and waders. But don't worry, we have the power to stop them in their tracks with just a few simple steps. So let's do our part and protect our waters from these unwanted invaders.
History & Status of the Fishery
A temperature-dissolved oxygen profile was collected in the deepest basin on Bertha Lake on August 8th, 2023 to evaluate the amount of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Whitefish and Cisco, also known as Tullibee. Based on the profile, the top of the thermocline (i.e., the location in the water column with the sharpest transition from warm to cold water) occurred at approximately 17 feet. Dissolved oxygen decreased to below 3.0 mg/L at 37.1 feet, which was below the thermocline, at the time of sampling. The temperature at which dissolved oxygen decreased to below 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 6.7?C (44.1?F).
TDO3 values cooler than 17.2?C for Lake Whitefish or 21.5?C for Cisco indicate that oxythermal conditions are favorable for these species. Dissolved oxygen concentrations below the thermocline indicate that suitable oxythermal habitat for these species was available across a range of depths at the time of sampling. Data collected in 1993, 1994, 1995, 1996, 1997, 1998, 2002, and 2022 also indicated suitable oxythermal habitat. When adequate oxythermal habitat is available, Lake Whitefish or Cisco are not squeezed into unfavorable, warmer water conditions and therefore do not experience higher levels of stress.
