Purpose

This data set includes drainage basins for fish passage sites that are barriers, or that had a Level B site assessment.

Abstract

King County fish passage barrier prioritization scoring and Level B assessment data processing requires site-specific drainage basins.

This dataset includes the area of land where precipitation collects and drains to a particular site.

These drainage areas are used to calculate a variety of prioritization metrics, including percent impervious and forest land cover, count and density of upstream barriers, plus sum of upstream stream length and IP score.

For sites where a Level B assessment was performed, the drainage area is used to calculate the low and high flow exceedence flows required to determine if a site is a barrier..
