A lack of large wood, resulting from low historic flows, extensive logging and mining activities, and the upper Trinity being cut off by Trinity Dam, has eliminated a valuable component of salmon habitat. Large wood has been installed at most TRRP rehabilitation sites on the Trinity River. Surveys are conducted as part of the Integrated Habitat Monitoring Project (IHAP) to understand how wood interacts with flows and rehabilitation features.
