The Coeur d’Alene Tribe’s efforts to protect and restore its waters were shared by nearly 1,000 scientists from around the country at the Society for Freshwater Science’s annual conference in Spokane, Washington, this week.
On May 19th, at the invitation of the Society, Councilman and Natural Resources Director Caj Matheson and Environmental Programs Manager Dr. Laura Laumatia gave the plenary talk, “Marking 25 years since Idaho v. U.S.,” to conference participants on Tuesday, focusing on the Tribe’s relationship to Coeur d’Alene Lake, as well as historic and contemporary threats to the lake’s health. Following the plenary session, Ralph Allan, Natural Resources Deputy Director, and Dr. Dale Chess, the Tribe’s senior limnologist, kicked off an all-day workshop focused on Indigenous leadership and collaborative partnerships in freshwater science.
Ralph shared the importance of research to the Tribe's restoration goals, while Dale shared the latest data on Coeur d’Alene Lake, as well as other departmental research initiatives. Following their talks, Natural Resource interns Brutis SiJohn and Serenity Martinez, both second-year undergraduate Tribal members in engineering and science, shared their field learning experiences with the Department and how they have shaped their educational journeys.
The presenters were joined by additional staff from Water Resources and EPO at the conference, where they also heard from representatives of the Spokane Tribe, the Karuk Tribe, the Kootenai Tribe, the Shoshone-Bannock Tribes, and Tribal undergraduates from Fort Lewis, as well as numerous presenters from universities around the country, all focused on ecological restoration of lakes, rivers, and streams.
In addition to the events in Spokane, a number of Natural Resources staff were also representing the Department on Tuesday at the annual Youth Water Summit in Coeur d’Alene, where Climate Resilience Coordinator and Tribal member Aiyana James opened the event by sharing her educational journey and the climate resilience work she leads on the Reservation. Staff from across the department participated in judging student projects that are the culminating event for nearly 300 high school participants in The Confluence Project, a field-based water quality and water quantity project coordinated by the Idaho Water Research Resource Institute in partnership with the Coeur d’Alene Tribe, UI Extension, and IDEQ.
The Department is proud to share with, and learn from, its partners in environmental restoration!
