Seasonal streamflow-metric trends for four United States coastal regions, 1943 through 2022

The streamflow trends in this data release were computed as part of a study on trends in seasonal streamflows relevant to diadromous fish in four United States coastal regions. We investigated seasonal-flow trends at 1,155 gages for eight streamflow metrics from 1973 to 2022 and 89 gages from 1943 to 2022. Two of the regions are on the Pacific coast and two are on the Atlantic coast.
