the dams built as a result of the treaty have altered the river's ecology and contributed to the decline of salmon fisheries. So in a 1995 opinion on the impacts of the entire Columbia River power system on salmon. Noah, the National Oceanographic Association, had set flow objectives at each of the Columbia River basin dams. In the last 20 years, the spring target has been missed roughly 27% of the time. So 27% of the time, there's not adequate flow at these dams for salmon to pass. And in the initial studies about renegotiation, the US and Canadian entities didn't address any of these ecosystem needs. They only addressed updating the power and flood control agreements, although subsequent documents have addressed incorporating more ecosystem-based function requirements. So you can see here on this map on the right, where there are salmon passages and where the dams have prevented any kind of fish migration. So everything north, almost everything north of the Canadian border, the salmon habitat has been completely destroyed. And in particular, groups that have been harmed by the original treaty and who have advocated consistently for considering salmon habitats are the Canadian First Nations and United States Native American tribes. And you can see here on the right
