Jimsmith Lake Foreshore Inventory Mapping Open 2010

System (FISS), the lake and its tributaries historically supported resident populations of burbot, rainbow trout, and westslope cutthroat trout. Over time, rainbow and cutthroat trout have been replaced by non-native game fish including eastern brook trout, largemouth bass, and yellow perch. Coarse species such as redside shiner also occur, which provide forage for other fish.

The shoreline and associated riparian areas also provide important habitat for a wide variety of wildlife species, including raptors (e.g., osprey, bald eagles), songbirds, large game (e.g., deer and moose), and numerous other species of birds and small mammals.
