Long-term Monitoring

The primary research focus for Fraser has been the effect of management practices on water yield and quality. Snow depth and water content are collected on four gauged watersheds, with records dating to 1941 for one watershed. Streamflow is monitored on four watersheds and two subbasins, and a continuous record of streamflow for the oldest watersheds dates from 1941-1943. Sediment transport and bedload are measured periodically. Climate (precipitation and temperature) is measured at 7 stations and records are available from 1969 (one location from 1939). Tree growth, seed production, and tree mortality records begin in 1938.
