Snags provide habitat for a wide range of organisms from cavity-nesting birds to insects, and are critical for maintaining forest biodiversity. Resource managers can create snags by topping trees to mitigate loss of snags to timber harvest, but information regarding changes in habitat for snag-dependent wildlife over time as created snags decay is lacking.

A U.S. Geological Survey streamflow gaging station collects water data on the Trask River. The Trask River gage is located near Tillamook, Ore. and has been in operation for 17 years.  

Trask River stage, discharge, and water-quality data are collected and used together to help monitor the current health of the river. Data from the river are sent to equipment in the gage house, where it is stored then transmitted to USGS servers. 

The Kalispel Tribe in northeastern Washington is located along the Pend Oreille River, home to culturally important, cold-water fish, such as bull trout and cutthroat trout.

A crew surveys Upper Whitehorse Creek in SE Oregon and finds a stretch of stream that dries up, or runs underground.

The popping and cracking of ice in lakes within the Newberry Volcano caldera is picked up by local seismic stations, such as Central Pumice Cone. The lake-ice quakes do not resemble standard volcanic low-frequency or high-frequency events and are sporadically observed in the winter at other ice-covered lakes in Yellowstone, Long Valley, and elsewhere.
