The average Tarr values were essentially the same as the peak summer water
temperatures for each population (the difference was 0–0.3 C), and the rank order of Tarr
among populations matched the order of peak summer water temperatures. Interestingly,
43 % of the individuals we examined had a Tarr that was less than the peak summer water
temperatures (LaHave: 46 %, Sebago: 37 %, Lac Saint-Jean: 46 %).
