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.

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.
