The Bonneville Flood was one of the largest floods on Earth. First discovered by G.K. Gilbert in the 1870s during his inspection of the outlet at Red Rock Pass, Idaho, it was rediscovered in the 1950s by Harold Malde and coworkers, leading to mapping and assessment of spectacular flood features along Marsh Creek, Portneuf River, and Snake River for over 1100 kilometers between the outlet and Lewiston, Idaho. The cataclysmic flood - from the rapid 115 meter drop of Lake Bonneville from the Bonneville level to the Provo level - was nearly 200 meters deep in places and flowed at a maximum rate of about 1 million cubic meters per second — about 100 times greater than any historical Snake River flood. Along its route the Bonneville Flood carved canyons and cataract complexes and built massive boulder bars. These flood features have been a rich source for understanding megaflood processes. Yet it still offers much more with new and developing techniques for hydrodynamic modeling and landscape analysis.

Presentation: Mist Gas FieldThe Mist Underground Gas Storage Field is located near the town of Mist, Oregon, approximately 60 miles northwest of Portland. In April 1979, the Mist Gas Field was the site of the first commercial natural gas discovery in the Pacific Northwest and has been actively explored since that date. Through the 1980s and into the 1990s, gas exploration and production in the Mist Field were carried out by Oregon Natural Gas Development (ONG), a subsidiary of NW Natural, in cooperation with a variety of industry participants. Numerous production wells were connected to Miller Station, the central gas processing facility operated by NW Natural, until December 1995 when all production-related operations were assigned to Enerfin Resources, a Houston-based exploration and production company. Miller Station is now utilized solely for the compression, dehydration, flow control and measurement of the gas flowing into or out of the storage reservoirs. More
The Oregon Lakes Association will be holding our Annual Lakes Conference October 25-26. Oral and poster presentations that kick off mid-day on Friday, October 25th and end mid-day on Saturday the 26th will cover a broad range of topics such as harmful algae blooms, water quality, lake and watershed restoration, aquatic invasive species, nutrient cycling, climate change, hydrology, and fauna and flora. Although high desert and mountain lakes are the focus of the conference, other types of lakes and reservoirs will also be covered (see the draft agenda).

Yumei Wang will present a challenge to develop new and transformative approaches for improving society’s resilience to future natural disasters.
The severity and consequences of disasters caused by natural hazards are greatly affected by the functionality of critical lifeline infrastructure after the events. The resilience of critical lifeline infrastructure – related to fuel, power, water, transportation, and communications – is essential for reducing the frequency and impact of future disasters.
