Lake Aeration

We use lake aeration as a fisheries management technique to provide Albertans with diverse recreational angling opportunities in areas of the province where such opportunities would be otherwise limited. Aerated waterbodies are typically shallow, eutrophic, experience prolonged ice cover, and are prone to summer and winter fish kills. Using aeration, we maintained dissolved oxygen levels above 3 mg/L to promote year-round survival and availability of larger fish to anglers. In 2021/22, we aerated 22 waterbodies across the province, all of which successfully overwintered stocked trout without any reported fish kills. This year, we expanded the aeration project by the addition of Peanut Lake, upgraded electrical infrastructure at Muir Lake and Coleman Fish and Game Pond, and installed additional subsurface diffusers at Kerbes Pond.
