pumps water and the fish over the dam. This seems to work on small scale dams of up to . Natural disasters Natural disasters are occurring more frequently due to climate change. Fires being more frequent means more obstacles for these Steelhead to complete their journey back upstream. Fires burning alongside our rivers and watersheds cause river pollution with debris and runoff. These reoccurring fires are also burning key vegetation alongside the rivers and watersheds that keep the water temperature cool while constantly being shaded. Vegetation alongside the water also helps with less evaporation occurring because of less direct sunlight beaming on it. History and cultivation Historically, trout have satisfied a necessary food source for human populations across the Pacific Northwest of the United States and British Columbia. Indigenous populations including the Salish of Middle Columbia River, the southern Okanagan, the Lillooet and Shuswap, the Thompson (N'laka'pamux), the Chilcotin, the Upper Kutenai (Kootenai), the Yukon Indigenous Peoples, the Caribou Inuit, the Eyak, the Micmac (Mi’kmaq), and the Montagnais (Innu) of Lake Melville, Labrador have historically utilized trout as a significant food source (Center for Indigenous Peoples' Nutrition and Environment). In particular, the steelhead is viewed as a prized fish, not only for its high-fat content and succulent orange meat but also for its connection to the native environment. Long-serving as an indicator for water quality, biological diversity, and overall ecosystem health, the steelhead reserves a particular degree of recognition and respect amongst human populations that have historically relied on the diversity of rivers, streams, and oceans for sustenance. Among others, the Southern Okanagan and the Lower Lillooet and Gitksan (Gitxsan) tribes relied on steelhead during the Spring seasons in March and April; the Tahltan tribes cultivated them during mid-March through April and in September; the Coeur d’Alene tribes depended on Steelhead Trout from May through October and November through April; the Upper Lillooet from fall through spring, and finally the Bella Coola (Nuxalk) and Central Coast Salish tribes enjoyed steelhead year-round (Center for Indigenous Peoples' Nutrition and Environment). The Steelhead Trout is celebrated for its service as a main traditional food source for historic indigenous populations. Some tribes, such as the Gitksan and Wet’suwet’en, even considered steelhead as their most important food source (Center for Indigenous Peoples' Nutrition and Environment). Tribal cultivation techniques Traditional cultivation methods of the Steelhead Trout by indigenous tribes included weirs used to re-direct the passage
