Bathymetric map and area/capacity table for Castle Lake, Washington
Adam R. Mosbrucker, Kurt R. Spicer
2017, Open-File Report 2017-1145
The May 18, 1980, eruption of Mount St. Helens produced a 2.5-cubic-kilometer debris avalanche that dammed South Fork Castle Creek, causing Castle Lake to form behind a 20-meter-tall blockage. Risk of a catastrophic breach of the newly impounded lake led to outlet channel stabilization work, aggressive monitoring programs, mapping...

Daren M. Carlisle, Theodore E. Grantham, Ken Eng, David M. Wolock
2017, Freshwater Science (36) 927-940
Protecting the health of streams and rivers requires identifying ecologically significant attributes of the natural flow regime. Streamflow regimes are routinely quantified using a plethora of hydrologic metrics (HMs), most of which have unknown relevance to biological communities. At regional and national scales, we evaluated which of 509 commonly used...
