We determined the distributions of Chinook salmon and rainbow trout by describing seasonal mean vertical and bathymetric catch depths from 1997 to 2005 using angler creel surveys. We developed and applied a cross-validated model of Lake Ontario temperatures to determine the water temperatures associated with these distributions. During April, Chinook salmon and rainbow trout were found nearshore at a bathymetric depth of 20*m. However, rainbow trout were caught at shallower vertical depths (4 to 6*m) than Chinook salmon (8 to 10*m). Both species moved deeper and farther offshore during May, June, and July. Vertical catch depths were similar, but rainbow...</br>
