New Lake Aeration Development

Alberta Conservation Association’s (ACA) Lake Aeration Project promotes angling opportunities in stocked waterbodies across Alberta where such fishing opportunities are otherwise limited. Waterbodies we aerated are prone to fish kills during winter and summer months due to low dissolved oxygen (DO), but with aeration, we maintain DO concentrations at levels that promote year-round survival of stocked trout. Each year, we receive several requests to aerate waterbodies throughout the province. Given the substantial cost associated with aeration operations, we carefully screen candidate waterbodies to ensure that we address top Government of Alberta (GoA) provincial-level priorities. In 2022/23, we screened two waterbodies, Chatwin Lake and Blue Ridge Pit Pond, by monitoring DO and temperature profiles during winter months. With assistance of local GoA (Cold Lake fish hatchery) staff, this is the third year collecting DO and temperature data at Chatwin Lake, and our first year at Blue Ridge Pit Pond.
