Transboundary Rivers Baseline Water Quality Monitoring Project

Taku River summary

Taku Water Quality Sampling Project:

Central Council Tlingit & Haida Indian Tribes of Alaska (Central Council) received a grant from the U.S. Bureau of Indian Affairs (BIA) to collect baseline water quality data on three major transboundary rivers. This project was developed in response to several current and proposed large-scale mines located on three transboundary rivers – the Taku, the Stikine, and the Unuk – that flow out of British Columbia and into Southeast Alaska.

Central Council collaborated with Douglas Indian Association the local federally recognized tribe of the Taku River and watershed area. Bernadine DeAsis, John Morris of Douglas Indian Association, Jennifer Hanlon of CCTHITA, and Cathy Needham of Kai Environmental traveled to the Taku River to begin a three-year baseline water quality study funded by the Bureau of Indian Affairs.

Testing was done on a monthly basis as weather and time permitted. The goal was to produce comprehensive, statistically valid, and scientifically defensible baseline water quality data to ensure management decisions are based on scientifically sound data. The study will look at the levels of heavy metals and other toxic substances from proposed mines in Canada that threaten Southeast Alaska’s Trans-Boundary Rivers. Baseline Data will be shared with the State of Alaska, the United States Environmental Protection Agency, regulatory agencies in British Columbia and the general public. Canada is not subject to the type of environmental scrutiny that we take for granted in the U.S.
