As part of a multi-year field program monitoring sediment transport and gravel conditions, NHC used underwater cameras and freeze cores to inspect the condition of placed spawning substrate. This revealed that there are significant spatial differences in the distribution of fine gravel and sand that infill the spawning sediments. To further investigate transport rates and develop an understanding of sediment mobility, NHC has implemented a bedload and suspended sediment sampling program. To provide cost effective data, NHC staff trained local operators and worked with local First Nation contractors to collect the samples. NHC also installed a turbidity sensor as a means of investigating the temporal patterns of sediment transport. In the end, the data collected showed that sediment transport rates were relatively low and the supply of sediment could be exhausted on the Nechako River.
