USGS Hydrologist Randy Host performs compass calibrations for discharge measurements at the Unuk River. The Unuk River is one of the transboundary watersheds of Southeast Alaska. This site has a Super Gage which is a conventional streamflow gage equipped with continuous water-quality monitors.
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).
Current and Historical Streamflow and Water Quality Data for the Unuk River
The Unuk River is the second smallest watershed in this study but has three large mining projects in development (Kerr-Sulplherets-Mitchell (KSM), Brucejack, and Eskay Creek). The U.S. portion of the watershed is within Misty Fjords National Monument, a wilderness area in Tongass National Forest. Within Canada are Lava Forks Park and Border Lake Park. Although predominantly a braided river, there are two lava canyons on the mainstem of the Unuk where water pours out of lava tubes. The Unuk is a very remote watershed that receives few visitors each year. Water quality sampling on the Unuk began in January 2018.

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...
Stikine River
The Stikine River near Wrangell and Petersburg is the largest watershed in the transboundary study of Southeast Alaska.
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.
Salmon River
The Salmon River, located near Hyder, Alaska, and Stewart, British Columbia, is the smallest watershed in the transboundary study of Southeast Alaska.
Suspended-Sediment and Solids Sampling
Suspended-sediment samples are collected on each visit at both gage and border site locations.
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.
