Lake Aeration

At ACA, we use 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 maintain dissolved oxygen levels above 3 mg/L to promote year-round survival and availability of larger fish to anglers. In 2019/20, we aerated 19 waterbodies across the province, all of which successfully overwintered fish without any reported fish kills. We established new financial partnerships with Mercer Peace River and Municipal District of Clear Hills at Sulphur Lake, and Saddle Hills County and Weyehauser Grand Prairie Lumber at Spring Lake (NW), and continue to maintain financial and in-kind partnerships for existing aeration projects.
