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. Streamflow and water-quality data can typically be viewed online in real time.
