Lake trout Salvelinus namaycush were captured in June and July, 1996, from Harding Lake using sinking, multifilament gillnets. Twelve fish (FL > 550 mm) were captured and fitted with high power, high frequency (149 mHz), externally mounted radio tags and released. The 12 fish were radio-tracked once during July and August and two to three times per week from September 9 through October 3 (spawning season) to assess potential spawning locations. Spawning aggregations were then located visually and the number of fish present counted. Two spawning locations were positively identified by visual confirmation of 10 or more fish at the same location on more than three occasions. A possible third spawning location was identified. Radio-tracked fish were located at this site on seven different occasions but only two additional fish were visually observed on each of two different occasions.
