Abstract: The Chilliwack, Alouette and Salmon rivers showed a similar pattern of faunistic zonation of fishes in spite of differences in size, temperature and discharge patterns. Low gradient, downstream areas supported a mixed fish fauna primarily cyprinids, suckers, sticklebacks and cottids. Areas of steeper gradient supported coho salmon and trout. Mountain whitefish coexisted with trout and coho in the steep gradient areas of the Chilliwack River. In the steep areas of the Alouette River, longnose dace coexisted with trout and coho. In the Salmon River, stickleback occurred with trout and coho in most of the steep gradient areas. Growth rates of trout and coho are presented for a period from 1959 to 1962. Summer growth rates of coho and steelhead were depressed by cool water temperature and high discharge in the Chilliwack River. High summer water temperature in the Alouette River may have reduced survival of steelhead trout. An attempt is made to relate differences in age class strength in the Chilliwack and Alouette rivers to differences in temperature and discharge conditions.
