    • Massachusetts hydrologic unit subdivisions

    Metadata Updated: January 22, 2026

    Impervious surfaces such as paved roads, parking lots, and building roofs can affect the natural streamflow patterns and ecosystems of nearby streams. This data set summarizes the percent of impervious surface for hydrologic units in Massachusetts using a newly available statewide 1-m binary raster dataset of impervious surface for 2005. A hydrologic unit consists of all or part of a drainage basin, or an area of coastal drainage. Hydrologic units subdivide large drainage basins into discrete, non-overlapping areas. This is one of three data layers in this data series publication.
