Hi Daniel, here's the link to the article at the USGS: http://pubs.er.usgs.gov/publication/70017659 Unfortunately, it doesn't look like they have a digital copy of the article. However in the abstract, it does mention this: "The peak discharge of this flow at a location 22 km downstream from the volcano was estimated to be between 12,000 and 60,000 m3 per second." Hopefully that's helpful, or can move you on further. Thanks! -Seth -------- Daniel King wrote: Hello, I'm trying to find nay information regarding drift river outburst, specifically the peak streamflow. I found an article that seemed to discuss the 1990 outbursts, but I can't find a copy of the article: Hydrologic hazards in the lower Drift River Basin associated with the 1989-1990 eruptions of Redoubt Volcano, Alaska Any help on this issue would be beneficial, thank you.
