The experimental removal of riparian vegetation was performed to determine the impact on stream temperature. Water that flows through the unbuffered creeks heats more than the water in the buffered creeks. As a consequence, the diurnal change in temperature is greater in the unbuffered creeks. We do not know many of the moderating forces on heat loading that may be at work in northern Interior streams. As a result we have heated selected streams to uncouple changes in temperature from other aspects of the natural environment that often co-vary with temperature. Energy put in as heat is transmitted a considerable distance downstream. The loss of heat after increasing stream temperature at a single point, however, appears to be independent of riparian zone characteristics.
