USGS Transboundary River Monitoring in Southeast Alaska
The USGS Alaska Science Center operates super gages on the Alsek, Taku, Stikine, Unuk and Salmon Rivers. Discrete water quality, sediment, and biological sampling are also collected at each gage location. Discrete water quality samples are also collected annually at the Canada-Alaska border crossings of the Taku, Stikine, and Unuk Rivers. Water quality data collection began in 2018 on the Unuk...
Integrating Stream Discharge and Temperature Monitoring for Tribal Partners in Southeast Alaska
Stream discharge and temperature patterns are being altered by climate change, but documenting these changes on the community level is challenging without community partners trained in suitable data collection techniques. The USGS Juneau Field Office is collaborating with the Yakutat Tlingit Tribe (YTT), the Southeast Alaska Tribal Ocean Research (SEATOR) network, and the Southeast Alaska Watershe
Suspended-Sediment and Solids Sampling
Suspended-sediment samples are collected on each visit at both gage and border site locations.
Unuk River
The Unuk River is the second smallest watershed in the transboundary study of Southeast Alaska, but has three large mining projects in development (Kerr-Sulplherets-Mitchell (KSM), Brucejack, and Eskay Creek).
Taku River
Adverse water quality from a trio of historic mines in the Tulsequah River watershed, a tributary of the Taku River, have caused concern in local communities including Juneau, Alaska, and Atlin, British Columbia
Alsek River
The Alsek River is the furthest north watershed in the transboundary study of Southeast Alaska, reaching 300 miles north of Haines Junction, Yukon Territory.
Super Gages and Water Quality Sampling
Super gages provide real-time data specifically designed to improve understanding of watershed processes and to address specific water-resource issues such as climate and land-use effects or hazardous substance spills.
Stikine River
The Stikine River near Wrangell and Petersburg is the largest watershed in the transboundary study of Southeast Alaska.
Salmon River
The Salmon River, located near Hyder, Alaska, and Stewart, British Columbia, is the smallest watershed in the transboundary study of Southeast Alaska.

Unuk River waterfalls from old lava pipes
Unuk River waterfalls from old lava pipes. Volcanic lava pipes form as the result of violent eruptions of deep-origin volcanoes. The Unuk River is one of the transboundary watersheds of Southeast Alaska.
