Tidal flux measurement in Sinclair Inlet
Scientists demonstrate equipment used to measure fluxes between groundwater and surface water. These interactions are particularly complex in tidally influenced shorelines such as Sinclair Inlet, WA.

Sediment deposited in delta of Conconully Reservoir, Washington
Sediment deposited in delta of Conconully Reservoir, WashingtonA shovel rests against a massive deposit of coarse sediment on the delta to Conconully Reservoir in Okanogan County, Washington. The sediment was deposited following the 2021 Muckamuck fire and a debris flow in July 2022. USGS scientists are studying the sediment and water quality in rivers and reservoirs impacted by the large fire.
