Abstract
Significant Findings
An analysis of sediment transport in the North Santiam River basin during water years 2005-08 indicated that:
Two-thirds of sediment input to Detroit Lake originated in the upper North Santiam River subbasin.
Two-thirds of the sediment transported past Geren Island originated in the Little North Santiam River subbasin.
The highest annual suspended-sediment load at any of the monitoring stations was the result of a debris flow on November 6, 2006, on Mount Jefferson.
About 86 percent of the total sediment input to Detroit Lake was trapped in the lake, whereas 14 percent was transported farther downstream.
More than 80 percent of the sediment transport in the basin was in November, December, and January.
The variance in the annual suspended-sediment loads was better explained by the magnitude of the annual peak streamflow than by the annual mean streamflow.
