Green River Near Auburn, WA
USGS monitors streamflow and sediment at the Green River Near Auburn, WA. In December 2025, a storm event raised water levels and increased the turbidity (muddiness) of the river.

Sediment sampling at Big Soos Creek, WA
A hand-held sampler is used to collect suspended sediment concentration (SSC) data from Big Soos Creek, WA. SSC data helps USGS scientists understand sediment dynamics in rivers.

Sampling water quality on the NF Skokomish River
USGS and NPS scientists collect a water quality sample from the NF Skokomish River. They lower a sampling device from the bridge to obtain a representative sample. Interagency coordination allowed rapid data collection after the fire.
