What is known comes entirely from the stocking record. Centaur received 12 recorded plants of brook trout between 1957 and 2001, the last a release of 1,000 fingerling brook trout of the Aylmer strain in 2001. Nothing has been stocked since, so any fish present today are either long-lived holdovers or a naturalized population sustaining itself in the lake. Until that is confirmed, plan on Centaur fishing like a small brook trout stillwater: chironomids and small nymphs worked over the shoals, with attractor dries a possibility if fish are rising.
