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

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.
