Layer: Tier II Stream Segments 2022 (1)

Name: Tier II Stream Segments 2022

Display Field: T2_SGMT_ID

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This dataset consists of a digital geospatial representation of all identified Tier II segments in the State of Maryland. Based on data collected between 1995-2019, this dataset currently contains information for 263 designated Tier II stream segments. Main segment breakpoints were determined using the 100,000:1 National Hydrography Dataset (NHD). The final designated Tier II segments are the merged sub segments that make up the 24,000:1 NHD meeting the 100,000:1 breakpoints. Tier II stream segments generally terminate at confluences, impoundment outfalls, and tidal boundaries.

Layer: Tier II AC Catchments 2022 (2)

Name: Tier II AC Catchments 2022

Display Field: CATCHMENT

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset represents the ‘nested’ Tier II catchments, 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. Nested catchments 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 165 Tier II catchments.
