There is a Tatshenshini near Dalton gauge maintained by the Water Survey of Canada's waterweb. It's a real-time station and you can view past discharge data. Readings are either in stage or discharge (cubic meters per second; to convert to cfs multiply by 35.7). There are two Alsek River real-time gauges: near the take-out, below the Tatshenshini confluence, and above the confluence, above Bates River.
