Name: Tier II Catchments 2021

Display Field: CATCHMENT

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset represents the final version of Tier II catchments used for assimilative capacity determination, or watersheds located within the State of Maryland. Oftentimes multiple designated Tier II streams (with their own individual watersheds) occur within a common, larger watershed. Supercatchments are those watersheds whose surface areas drain to the most downstream Tier II stream segment in a collective watershed area. Based on data collected between 1995-2019, this dataset currently contains information for 195 Tier II catchments.
