Sediment samplers are designed to obtain representative samples across all depths and locations in a river cross-section. This is important because sediment concentrations are not always consistent across the channel. This D-74 sampler weighs 62 pounds and can sample in velocities up to 6.6 feet per second and depths up to 15 feet. It has been in use since 1974.

Multiscale comparison of hyperspectral reflectance from periphyton in three Oregon rivers used for municipal supply
In this study, USGS scientists from multiple centers used advanced hyperspectral imaging techniques to advance monitoring of attached benthic algae (periphyton) in Cascade Range rivers used for municipal water supply. Periphyton are naturally occurring, but excess growth can harm ecosystems and degrade raw and treated drinking water quality. In these rivers, periphyton contain cyanobacteria that...
